 Allergy Guard

  • Advanced Nano Screen
  • Construction = High strength PVC-coated synthetic fiber construction with integrated Allergy Guard nano-fiber filtration media

REVIEW OF MICRONS & NANOMETER SIZES

  • 1 meter = 100 centimeters
  • 1 centimeter = 10 millimeters
  • 1 millimeter = 1000 microns (μm) (also called micrometers but we will use microns)
  • 1 micron (μm) = 1000 nanometers
  • Micron (μm) = Micrometer = 1000 times smaller than a millimeter
  • 1000 microns (μm) = 1 millimeter (mm)
  • 1 micron (μm) = 1000 nanometers
  •  Nanometer (nm) = 1000 times smaller than a micron (μm)
  • 1 nm = 1 billionth of a meter

NOTE THAT A NANOMETER IS VERY, VERY SMALL.   MUCH SMALLER THAN A MICRON

  •  General / macro virus size range spectrum = 20 - 300 nm
  • Factory R&D States // Coronavirus Size Range = 0.1 – 0.3 microns (μm)

Allergy Guard Mesh = Blocks very small particle size range of 0.02 microns (μm) = 20 nm and above

The Allergy Guard nanofiber filtration capacity covers the full virus particle size spectrum

  • - Independent cross-check / Britannica / stated Coronavirus size = 120 nm = 0.12 microns (μm)
  • - Independent cross check / Stanford University / stated Coronavirus size = 80-160 nm = 0.08 – 0.16 microns (μm)
  • - Independent cross-check / Smart Air Filters.com / Stated Coronavirus size = approx 125 nm = 0.125 microns average in a range of 0.06 - 0.14 microns (μm)
  • - Other Reference // BMT File / Electron microscope photo coronavirus size = 100 nm = 0.1 microns (μm) 
  • REFERENCE ONLY // COMMON MARKET N95 MASK / DEFINITION = A typical market N95 mask is a type of respirator which removes particles from the air that are breathed through it.
  • These respirators filter out at least 95% of very small (0.3 micron) particles.
  • N95 masks are capable of filtering out all types of particles, including bacteria and viruses.
  •  Allergy Guard can filter out much finer particle sizes as noted above.

 

Customer Experience:

"OMG! The pollen has started in earnest and guess what?! These screens are keeping the house pollen free! I cannot believe it. I am going to do the master bedroom screens tomorrow as it is a dust bowl. Yech! 

I will take some pictures to show the difference. It is amazing. I am so pleased. Well, I am going to post on local forums and FB pages about this. . Can I put your name and 800# out there?"

Cheers  Angela

Metro Screenworks Inc. is introducing the latest in window screening material technology. We can manufacture window screens with Allergy Guard or provide rolls of Allergy Guard for you to install in your existing screens or any opening as needed. This multi-purpose window air filter screen is a must to protect your family from the pollution that is a growing problem in today's world.

 Allergy Guard is a high-performance, nano-fiber window screen mesh. This window screen filter is an advanced home and institutional nano-fiber screen mesh for window screens engineered to block most airborne allergens and ultra-fine dust:

  • Filters out fine Ultra fine dust PM 2.5 and fine dust PM 10. Also Yellow dusts and pollen, ultra-fine dust, and more!
  • Unlike conventional window screens, Allergy Guard blocks most bacteria, fly ash, pollen, hair, and agricultural & airborne dust. These window dust filter screens form a defensive barrier to prevent entry into the home or office.

  • They also have excellent filtering efficiency to block ultra-fine particulate matter & allergens down to 300 nanometers.

  • By comparison, the standard window fly screen only filters much larger particles the size of 2,000,000 nanometers.

  • These pollen screens have high porosity 80-85% = High permeability for excellent air circulation.

  • The high strength 3-layer construction provides superior durability.

  • These window filter screens also block 95% of rain and water.

  • They also provide excellent visibility while blocking more than 90% of UV light and 50% of infrared light.
