InvisiClean Replacement Activated Carbon Prefilter - 4 Pack - Genuine Prefilter for InvisiClean Claro Air Purifier IC-4524

These replacement filters fit perfectly and were exactly what I needed. They are lightweight, easy to replace, and work well for helping keep the room cleaner, which was the main reason I purchased them. I was pleasantly surprised by how long each filter lasts. Having a multi-pack is also really convenient because I always have extras on hand when it's time to change one. Overall, these are a great value and a simple, practical replacement. They fit as expected, are easy to use, and do exactly what I needed them to do. I would definitely purchase them again.

These filters work very well. I have three of the InvisiClean air purifiers in my house, and they all run constantly. These three machines are located in two bedrooms and in the den. I have cats, so the most visible sign that the filters work is the amount of cat fur they catch. I vacuum them clean every Sunday, as all three filters are visibly loaded after running constantly for a week. My subjective view is that--for my house--I should probably replace the filters monthly, because they seem to lose a bit of their power after that, but I stretch them out for three months. When I replace the filters, the HEPA filter underneath looks dirty, but that seems to be mostly just carbon from the pre-filters. I'm happy with the results I get from my InvisiClean products.

Expensive for a disposable item.

Very good. I like it.

only drawback is you can only get these from InvisiClean cut to fit. Makes them a bit pricy.

Just as described. Do a great job, easy to install. Good value for the price.

I had a little trouble figuring out how to make it stay in place but it definitely does the trick with keeping the air clean

I bought these for my Invisiclean air purifier. They fit as they should and work fine. The only negative is these are insanely expensive for what amounts to a thin piece of foam material.
