InvisiClean Replacement Activated Carbon Prefilter

They work well as the pre-filter for my InvisiClean air purifier. It helps me save on the large filters. I have actually washed and reused them but only for 1 more use before replacement with a new one.

Good monthly replacement of the carbon filter. These extend the usage life of the hepa filter (in a sense) as they replace the carbon outside filter that can get pretty dusty/dirty fast. I replace this one about every other month and the hepa one twice a year and my filters seem to work pretty well.

This was a repeat purchase so my review is of an earlier batch. These filters are efficient at eliminating odors and catching dust by the Invisiclean Sensa air purifier. I use a handheld vacuum cleaner to clean after a month or two, then change the carbon filter the next time. When after changing just the charcoal filter, the air purifier still shows the Change Filter sign, I change the entire filter - the HEPA and the activated charcoal filters. This lowers the cost of running the air purifier since the HEPA filters cost a lot more.

If you own this air cleaner you must get these. You will extend the life of your filter. Just don't wait to long between changes. I replace this pre-filter every other month and replace the complete filter and pre-filter every 8 months.

Reasonable price, easy to clean and last a long time.

These filters are great! They really clean the air. I have bad allergies & asthma and they really help clean the air. (Please disregard previous review. I thought the size was incorrect but it’s perfect)

These are good filters and exactly like the one that came with my air purifier.

No smell

I love the purifier and these carbon filters. I feel like it actually traps all the dust because every time I’m notified to change filter I can see how much dust is accumulated on it. My daughter’s room feels cleaner because of it. Totally recommend it!
