Great Quality at an Affordable Price
This 45i replacement cartridge is exactly what I needed for my air purifier. The quality is excellent—it fits perfectly, works just as well as the original, and helps keep the air in my home feeling clean and fresh. What really makes this a great buy is the affordable price without sacrificing performance. It’s a solid option for anyone looking to maintain their purifier without overpaying for name-brand filters. I’ll definitely be purchasing this again when it’s time for the next replacement!

Great replacement filters!
I was very happy to find an alternative to the expensive Alen brand filters. These look exactly the same as the Alen ones, and they fit perfectly. They seem to be working very well too. I also appreciate that they come with extra pre filters.

It does what it says at way less money
I have nothing bad to say. They seem to be good. People who say that is still shows “change filter” probably didn’t just reset the filter button. Seem to work for me.

Fits perfectly well
Fits well and is durable. Air purifier seems to work just as efficiently as with the brand name filters, at a fraction of the cost.
