Medify MA-40 Air Purifier with True HEPA H13 Filter | 1,793 ft² Coverage in 1hr for Smoke, Wildfires, Odors, Pollen, Pets | Quiet 99.9% Removal to 0.1 Microns | White, 1-Pack

The size is very accurate. The noise level of the machine varies. The fit of the filter into the machine is accurate, Ease-of-use is very easy installation. The ease of replacement is extremely easy and the quality is great.

Perfect fit, original quality filter.

Perfect

I had plan to order this on their main site as I have done before, but it's quicker and easier to order directly from Amazon. It was also slightly cheaper. The quality is there and it is not a knockoff. I appreciate the quality and the effort that Medify puts in their air purifiers. It has definitely made a difference in my house and I will be buying more purifiers in the future.

2nd purchase : 2025 3rd photo attached is the most recent purchase. It is indeed expensive, i still wonder if there's a comparable replacement generic brand. - The air purifier filter worked well and improved the air quality, but it didn’t last as long as advertised—it needed replacing in less than 6 months. Replacing it was easy, but it’s pretty expensive. I decided to stick with the original brand because I wasn’t sure about using a generic one. I’ve attached a comparison of the used and new filters to show the difference.

Perfect fit.

Amazon put 30 lb water case on the box and inner box did not sustain damage! Great packaging!

I've purchased both this and the generic two pack version that's much cheaper in price. From my experience from both I say go with this more expensive version. It's worth it and you do get that you pay for. The generic two pack I could literally smell the difference in air quality. They also left the base around the filter dirty as if they weren't attracting all the dirt in & etc and so it seemed as if it were kicking it back out. Even the air purify machine was black on the outside we noticed. With this manufacturer filter it doesn't do that, it picks up everything and keeps it within the filters and the purifier device is cleaner. I can also tell how much lighter the air is, at least because it smells cleaner and is trapping the particles. Even when I'm not paying any attention it's easy to remember how I feel with both running. Highly recommended!

Good quality filter that is bulky enough to trap contaminates with a good filter life

Not bad but don’t stay long like other brands filters I used in the past, that been said the price factor is making me understand as other brands might be more effective for much longer time the price of the filter is like 4 times more.

I love this filter. It is not cheap, but it is an excellent purchase. My dentist recommended it during the pandemic, so I bought it and don't regret it. I change the filter every 6 months.

Works fins
