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.

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.

Works fins

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.
