BEST HEPA FILTER SYSTEM ON THE MARKET

Absolutely the best HEPA Air Filter on the market. And of you have indoor pets, this is a must have. For anyone who has medical needs, suffers from allergies, Lives in a metro city area where air quality is usually a challenge or any/all those plus just wants a clear, clean, crisp, fresh air, look no further, this is the HEPA Filter system for you. Its worth 3x what it sells for, and worth every penny. Enjoy.
I would recommend this to a friend!

Told me I had clean air out of the box ...doubt it

I bought this 2 weeks ago. The minute I plugged it in it said air was 100%. I left it alone and in the next 48 hours- still at 100%. I tried the perfume test , spraying about a foot away from the back of the unit, it went on with the fans at 2 for about 15 minutes then went back to 100%/eco. I even left the patio door open with "very high" pollen count outside, never went on. I know I have dust and I can see dog hair all over my tile floors. Don't think this was worth the price tag.
No, I would not recommend this to a friend.

Best hepa air machine on the market
on March 7, 2026
Posted by: mom20072019
from VA
Gender:Female
Ours lasted about 2 years before it just stopped one day abd the screen showed to dash marks I assumed it meant the main filter had finally given out. Now we ran this thing hard daily 24/7 so a little over 2 years is acceptable in my opinion plus we have multiple long hair dogs, long hair cat, etc. This thing is an absolute work horse! Only reason not 5 stars is cannot find official replacement filter anywhere so cannot use without it!
I would recommend this to a friend!

Unfortunately not a very good filter.

Really doesn't work well with cigar smoke. The filter gets dirty very quickly so you have to constantly vacuum it to get rid of the particles. Not worth the price

Replacement filter never in stock
on February 12, 2026
Posted by: Gina775

Gender:Female
Bought this and now for almost a year I haven’t been able to get a new filter to replace the old one. Extremely frustrating when you can’t get the replacement you need especially when you live in a wild fire prone area in summer . You must have replacement items available or it makes the product expensive and useless!
No, I would not recommend this to a friend.
