se ve muy buen filtro

I buy these to wrap my HEPA replacement canisters with for my air purifiers. They easily extend the filter life of your HEPA cartridges by 2x-3x so the $10 or whatever is $ well spent. Using these I'm not feeling guilty about buying OEM replacement HEPA filters that cost more but do a far superior job. Every month or so I'll just take my HEBA cartridge out and vacuume the dust off this pre-filter and put it back in. Easy to cut and comes with 2 velcro straps to hold it in place if putting it around a circular filter. ALSO... I use the leftovers to cut rectangles out of to replace the lousy filters in my air fryer. 4 of them cut into little rectangles matches theh thickness of the 2 lousy filters my air fryer came with that do nothing as far as filtering out smells. These greatly reduce the smells air fryers emit. They don't eliminate it but do significantly reduce it.

The change of air quality is noticeable immediately...Excellent

Good value for the money
