Medify MA-40 Genuine Replacement Filter for Allergens, Smoke, Wildfires, Dust, Odors, Pollen, Pet Dander | 3 in 1 with Pre-filter, HEPA and Activated Carbon for Removal to 0.3 Microns | 1-Pack

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.

Perfect fit, original quality filter.

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.

Although the HEPA filters last a long time, the price is pretty steep, but worthwhile. What I like best is how quiet this room filter is and that it has been giving me good service for a few years.

Great air purifier with this filter but filter is too costly

As advertised

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!

Perfect fit.

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.
