Merv 13 est conçu pour piéger les particules microscopiques aussi petites que 0,3 microns. Assez petit pour arrêter la poussière fine, les allergènes, le pollen, les squames d'animaux et autres irritants aéroportés.
Pour atteindre le MERV-13, un filtre doit attraper 90% des particules dans la plage de 3-10 μm, 90% des particules dans la gamme 1-3 μm (où les PM2,5) et 50% des particules dans la plage de 0,3 à 1 μm.
Caractéristiques :
- - Hypoallergénique/non irritant.
- -Couche légère mais très protectrice.
- - Dimensions : 70 x 430 cm.
- -Véritable MERV-13.
- - Facile à insérer et à régler.
- - Doux et respirant
- - Sans fibre de verre.

Makes a great prefilter on drum and cartridge air cleaners, I replace one a month. Helps the OEM filters last longer.

I bought this material to filter air in my residence as an alternative to a hepa filter. The popular hack is to use a furnace filter attached to a box fan. This product is cheaper and can be cut to a variety of sizes, which I have done for a small personal evaporative cooler.The filtration rating on these higher rated furnace is not as high as a hepa filter, but it’s still very good.

A filter fabric should not produce more particles than what it's designed to catch. After about a month of use, I realized that the material is shedding microfibers.Their claims:- MIRV 13? NO! It is too thin! I'd like to see independent lab testing evidence that proves it's MIRV 13 - even with electrostatic charging, it's still unlikely to be more than MIRV 8.- Good for masks? Absolutely NOT! It sheds microfibers and this will pose a serious health risk if you breathe in these microfibers.I attached a side-view photo. The fibers "stick" to everything so it naturally pulls away.For a disposable air filter material, there is much better and safer material available.Thank goodness for Amazon's great return policy.
