For those who did not know, you can wash facemasks for re-use. The process is simple and easy to do. We felt the need to make a video to show just how easy this can be. The daily use of facemasks creates a higher demand for them, which lowers supply amounts. This effect raises the price for facemasks significantly. We thought we would help by providing an alternative solution to save people money!

Peter Sing’s New Invention Will Kill The Virus

Atmospheric air is drawn into the intake which goes directly into the first fan, compressing and forcing the air through the first filter. The air then passes through a reducer to compress the air once more. The newly compressed and filtered air then passes into another fan but this time the air is combined with the disinfectant at a high rate of speed causing the air and disinfectant to separate through centrifugal forces. The separated disinfectant then drains into a reservoir to be re-used while the separated air is forced through another reducer to a chamber that has optional UV light or added heat. The newly purified air then passes through conduit means into the breathing hood and is inhaled by the wearer. The breathing hood encompasses the wearer’s head entirely and is secured by a neck band around the wearer’s neck. Newly purified air flows into the breathing hood, this current holds the hood out of contact with the wearer except for where it is secured with the neck band. After the wearer exhales the air it is expelled through an exhaust port which returns the expelled air back to the processing chamber to purify the air once more before releasing the exhausted air back into the atmosphere.

Peter Sing’s Old Invention

This drawing is an example of the breathing hood described above, it was taken from Peter’s old patent #4,815,458.
Thanks to ‘ProactiveAndPrepared’ for creating this informational video.

The video above is an example of the breathing hood of the protective breathing apparatus described here. The main difference is that instead of the filter on the front of the hood (in the video), the breathing hood of the protective breathing apparatus will not have a filter. The filtration will come from the filtration/purifying device.

Thanks to ‘Vapour Engineers’ for creating this informational video.

The video above provides an example of how the filtration/purifying device operates. The main differences are that the protective breathing apparatus will be lightweight and portable, unlike the air scrubber which is usually very large and is used in industrious settings. Another difference is that the scrubbing solution in the air scrubber is water, the scrubbing solution is a disinfectant solution. The disinfectant solution will utilize soap and/or alcohol so that the solution can deteriorate any incoming virus particulates.

Here is where we will be posting all of the comments and critiques of the protective breathing apparatus. If you would like to add anything, please contact us at!

‘I think that we could simplify your design a little, to get the same “wash effect.”I am looking at rebreather designs, which use a sponge, brass wool, or similarly porous material that holds the liquids, and allows the air to pass through with lot’s of wetted surface area. Another variation are swamp coolers. This would eliminate the need for a rotating brush.A small pump to keep the surface wetted would be the only power draw.Here is a link to the concept: this concept could be scaled down to your filtration tube. Similar concept with a rebreather. The breathing air passes through a unit with a chemical solution in a porous material to keep it wetted and increase surface area:

Either way, a small fan to make up for the flow restriction, like that on a PAPR, would make breathing effortless.

I fully realize that valuable new ideas in the past have always been met with skeptics, and I don’t want to be dismissive when I may well be wrong.  But I have to say, I think you face a real uphill battle here for several reasons.
I did a little research on your competition, I see that 3M make a product, the Versaflo TR-300, and I used that as a basis of comparison and education.  One key fact is that this 3M device delivers 185 liters of air per minute.  You mentioned that you would sterilize air by mixing it with soap or alcohol.  Right off, we can eliminate the alcohol idea, evaporated alcohol vapor (that can’t be separated out) would not be tolerated at levels able to kill virus, I believe.  Even with soap, I worry about vapors from evaporation or incomplete separation in a centrifuge separator, being inhaled.  Even if substantially less than 185 liters would be adequate, say 90 (?), aerosolizing enough of a soap like product for this volume, mixing with air for an adequate amount of time, and then completely separating out this product at such high flow rates just doesn’t sound workable.
I like the UV light idea better, I found a UV-C sterilizing bulb that consumes only 6 Watts of power that perhaps could sterilize air flowing at such a high rate (???).  It only costs $3.01, so that’s affordable.  If you go this way, I don’t see that you could treat exhaust air with the same bulb, mixing intake and outflow takes much higher flow rates needed to dilute expired CO2 and allow enough O2.
I think with the trillions being spent on vaccination, you will find this a tough sell, even if you manage to overcome the many practical issues that will come up with adequate sterilization and affordable production.  Plus, people don’t want to wear a mask, let alone a hood, so that is a real issue.
I think your best chance of success would be to come up with a more affordable alternative that could be used in ER’s and stockpiled for future pandemics, but funding sounds like a challenge.
Sorry I’m not more excited, but that’s what I think at this point.


I see you already started your fund raising process.

To bring it to the commercialized Stage you might have to go through lots of haird
It is not easy to bring a concept to make it commercialized especially this type of extreme sensitive worldwide pandemic situation.
I hope your prototype model can be done soon, Selecting the final materials to be used are very important,
You should not mention in the Go fund me about the plastic Hood used costs only five cents each, you should just say “little cost” because you’re not certain what will be the final material Yet.? it has to be safe and pass many tests because there’s a lot of liability issues you have to consider,
I will think of more to share-

Anyway wish your success!

‘I have the same idea as your friend Vincent. Think the easiest would be modifying an existing PAPR system. Something like this:, but add your own disinfectant system. For mass acceptance, the whole thing need to be of lighter duty. If mass production of this is possible for $1000, US government can provide everyone with one for 400 Billion dollars, which is less than amount spent fighting this now. However, with the political climate, I just don’t see majority of people would wear this even if received for free from government. I still think a wet system would be too difficult to easily make into personal device.
For the “marketing release” you would need to add some pictures or drawings in order for people to better visualize this. I think another way to do this, instead of having personal protection system, is to modify existing HVAC system for all the indoor facilities, such as restaurants, mall, theaters, etc. If the virus can be effectively eliminated in the HVAC system, it would make indoor activities much safer and I think would help greatly in reduce the amount of transmission.’

High-end Veneer Doors

Sing Core specializes in increasing the performance, durability, and customer satisfaction in high-end veneer work in custom veneer doors of any size which can be guaranteed to remain warp-free for 50 years, including full structure warranty. No other method of manufacturing a large high-performance veneer door can achieve these results.

It all starts deep within the structure of any veneer door with Sing Core inside. Sing Core is the patented brainchild of inventor Peter Sing who conceived of the structure core which revolutionized the way doors were made.

Sing’s invention is basically a vertical grain torsion box core with small grid structure where the grid voids, which are usually left open in traditional torsion box, are filled with rigid foam insulation.

This composite base material is pressed between to stress skins to create Sing’s lightweight high strength high-end veneer door core.

The biggest and best door companies, millworks, and custom door manufacturers love it, and you will find them using Sing Core inside all their high-end custom large veneer doors. And that’s why you’ll find them at the top of the tallest building in the United States of America, World Trade Center 1‘s Freedom Tower.

16' Tall Oak Doors in One World Trade Center

Telegraphing and Crossbanding

The most environmentally conscious way to create a veneer door is with a thin veneer material, such as 0.020-inch veneer. The only problem with this thin veneer is telegraphing.

It is normal to crossband veneer, which basically doubles the price of the veneer, to prevent telegraphing.

Not necessary with Sing’s super-smooth veneer door blanks. He uses his patented veneer door technology to create an extremely smooth surface to lay veneer on flawlessly by using a thin later of MDF to accommodate the lamination of a thin veneer.

Problem solved.

Large Oversized Veneer Doors

When architects spec an architectural veneer door, if it is a very large door (anything over 8 ft tall or 4 ft wide) they are far better off going with a thin wood stave surface. Wood stave consists of wood planks cut into thicknesses of 1/8 to 1/4 -inch thickness. Then this solid wood is applied to Sing’s door blanks.

Veneer is normally limited in available lengths, whereas planks of specific wood species are generally available in longer lengths. This can accommodate the long length necessary for a vertical grain veneer door design.

Plus, if it’s done right, your high-precision large wood stave door with Sing’s core inside looks just like a solid wood door. Only it weighs far less than any other solid core door, and can be guaranteed not to warp, bend, twist, cup, or otherwise fail for 50 years.

And no other door can come backed with such an impressive guarantee.

Even though Sing’s doors are desired by nearly everyone, to have such a door may be cost-prohibitive for most. It is more common to find high-end veneer doors with Sing Core inside in the most expensive homes in the USA. You may find them used in scientific research, and anywhere in the world, from beneath the sea (US Navy) to outer space (NASA) and anywhere in between.

Once you’ve experienced a high-end veneer door of such magnitude, you will agree with the professionals who insist on using Sing’s patented solutions, that,

“It’s the only way to do it.”

Sing Core is the only way to build a big veneer door that can be guaranteed for 50 years. The only way.

Interior Sliding Barn Doors

It is not uncommon for interior sliding barn doors to be specified as metal barn doors, such as steel sliding barn doors and aluminum interior barn doors.

Natural wood species top the requests for interior sliding barn doors, by far. While contemporary architectural design fashion shifts dramatically, the most common natural wood grains specified for natural wood architectural doors are:

Top 10 Wood Interior Sliding Barn Doors

1. Pine Barn Door

2. Cedar Barn Door

3. Walnut Barn Door

4. Knotty Pine Barn Door

5. White Oak Barn Door

6. Alder Barn Door

7. Maple Barn Door

8. Hickory Barn Door

9. Mahogany Barn Door

10. Cherry Barn Door

And just in case you were wondering these other natural wood interior sliding barn doors follow the Top 10 in their order of popularity: Red oak, red cedar, teak, birch, ash, white pine, fir, hemlock, beech, and rosewood wood species.

Even though these natural wood species are the most popular, doesn’t mean you are limited by any means. The more high-end the project is, whether it is an exclusive commercial or residential structure, the doors could be specified as very exotic wood.

By using veneer doors as your interior sliding barn doors, you honor and preserve the natural resources by using very thin layers of the natural wood on the surface, which can end up looking like a solid wood door, if you do it right.

Natural wood veneered interior sliding barn doors are a conscious use of natural materials, whereas natural wood veneer may not be recommended for exterior doors. Wood veneer is too thin to be used in an exterior application, as it cannot take much abuse when exposed to the elements. In the case of exterior doors, it is best to stick with wood stave doors, using natural wood planks of at least 1/8” thick.

The Best Interior Sliding Barn Doors

The best interior sliding doors have Sing Core inside. You might ask, “What is Sing Core?” Sing Core is a patented core material invented by inventor, Peter Sing, who is also the president of Sing Core. His experience and fascination with aeronautics led him to create a lightweight high strength building material which could be used in the aerospace industry.

Who knew he would invent the most exclusive sliding barn door substrate material that could be used to build enormous interior sliding barn doors up to 50 ft. that weight a fraction of the weight of other wood-based solid core doors and are stronger than steel pound of pound (independently rated at 660+ PSI).

But Sing’s invention doesn’t stop there, Sing also pre-insulates every one of his door blanks to further enhance its features, such as increased climate control and built-in sound proofing for increased energy savings, safety, and security.

And on top of that, there is the unheard of guarantee that cannot be touched by any other method of building doors, with Sing’s own,

50-year Warp-Free Guarantee

Sing’s invention has enabled the biggest and best door manufacturers in the United States to build these large oversized sliding barn doors that can be guaranteed not to warp, bend, twist, cup, or otherwise fail (including structure and lamination) for 50 years, for flawless customer satisfaction.

Proudly manufactured with locally sourced materials and made in the USA by highly skilled craftspeople and artisans, the art of building customized warp-free substrates which are perfectly matched for any surface material and it’s inherit reaction to changes in the environment and tendency to move.

As Sing’s clients have been saying for more than 20 years, now,

“There’s no other way to do it.”

There is no other way to build a large door of any type or style and guarantee that it will basically never warp, guaranteed.

Mr. Sing says, I could not say it, if it wasn’t true. And If it wasn’t true, if even one door warped, I’d be out of business.”

Sing Core is the only way to build a warp-free interior sliding barn door, period.

Veneer Door

Veneer doors are the most responsible use of natural resources because the declining supply of available natural wood grains are mediated by slicing very thin layers of grain into sheets of natural material which can be applied to a flat surface, such as plywood, panels, or used as door skins.

Most Popular Veneer Doors

While the various wood grain varieties of doors change, some veneer types are more popular than others around the USA. Right now, the two most popular wood veneer doors are,

Walnut Veneer Doors       and       Oak Veneer Doors

Walnut and oak veneers are tied for first place in the world of veneer doors, followed by maple, birch, teak, mahogany, cherry, ash, cedar, and pine veneer doors, in that order.

A veneer door is indeed beautiful, but this elegance is only skin deep. The attributes of the veneer door’s underlayment are the key which greatly enhances or diminishes the appeal of your veneer door, which is the best predictor of your veneer door’s performance over time.

Veneer is an excellent way to build a standard-sized door, but when you are reaching for door heights which pass the 8 foot mark or widths that are greater than three-and-a-half feet wide, you start running into the risk of door failure.

Even if you run into a problem with a standard sized door, it’s not too much of a problem, because factories (most offshore) are churning these out by the thousands every day. So, when your door fails, you just run down to your local hardware store and buy an inexpensive replacement door and you are back in business. This is often less expensive than hiring a millwork to service or repair your veneer door.

Large Veneer Door

Large veneer doors are an entirely different animal. These oversized doors do not come off of a conveyor belt. They are usually a one-off build by a highly skilled artisan or team of craftsmen who are building these big veneered doors according to engineered architectural specifications.

There are many things to take into consideration for a large door with a natural wood veneer on it. The first consideration is the veneer, itself. How thick is it? What will the substrate be made of? How will it be applied to the substrate. If, laminated, what is the method used, what adhesive will be applied, and how long will the lamination last, before it starts to delaminate?

Wood veneered doors are more commonly used indoors, as the thin veneer is not well-suited for exposure to the elements, such as in a large front door application. In this case, you would be better off using a thicker surface material such as an eighth to a quarter inch-thick wood stave skin (planks) for exterior doors.

Most importantly, you want to pay close attention to how the door will be made from the inside out, especially in large veneer doors over a standard 3-0 7-0 door? Why? Because they will warp. Almost any material used in building an oversized veneer door will move according to variations in the environment where the door resides.

I say, “almost,” because there is one way to build a large veneer door that will not warp.

Warp-free Veneer Door

If there’s one thing that the high-end custom veneer door manufacturers know, it’s that if it’s large and, “If it doesn’t have Sing Core inside, there’s no warranty.” Why? Because all large veneer doors move. That is to say, they warp, bend, twist, or delaminate, because they do not have Sing Core inside. All due to the movement of the door over time which breaks down all the necessary components and compromises the operation of the door.

Thanks to inventor Peter Sing’s invention of his engineered composite hybrid warp-free veneer door core, doors can be made to remain straight and true for years to come. They are also the lightest weight strongest (stronger than steel pound for pound) door blanks in the world which are also fully insulated for added sound deadening and climate control capabilities.

Even though Sing says, “We do not build doors,” he is responsible for some of the biggest most beautiful doors in the world that deliver the highest precision (Sing’s core boasts +/- .006-in. tolerances) most sustainable doors in the world with unsurpassed longevity. Each door with Sing’s core inside can be backed by Sing’s unprecedented,

50-Year Warp-Free Guarantee

This is the truth. Sing guarantees his doors to remain warp-free for 50 years. He has been providing the biggest and best door companies in the nation with warp-free door core. And if you ask these door companies, “Why?” They answer,

“There’s no other way to do it.”

There is no other way to build a big veneer door that will not warp without Sing’s core. That’s why we rely on Peter Sing’s invention to deliver the goods. And, as Sing says, “If it wasn’t true. If I couldn’t do it, even once, I could never offer that guarantee again.” And he’s still here without even one warped door in ten years.

How do you get Sing Core?

Increasingly, Architects are specifying Sing Core in all their high end essential large door projects. But if you want one, all you have to do is to go to your local millwork or large custom door manufacturer, and tell them what you want, but be sure to tell them, “I want Sing Core inside,” and leave the rest up to us.

It takes a village to build a large veneered door.

Architects and engineer’s work on the concept and the design, then there are the door companies and millworks who are responsible for the hardware and finishing aesthetics, and finally fine craftsmen hang and install the door.

Your veneer door with Sing Core inside is a one of a kind work of art.

That’s why you find Sing’s core in the tallest doors in the tallest building, on the top floor of the Freedom Tower at World Trade Center in New York, and anywhere from beneath the sea (US Navy) to outer space (NASA).

Let us help bring your dream door to life.
