Review on 🌈 Colorfullife Replacement Filters for Holmes AER1 HEPA Type Total Air Filter - HAPF30AT and HAP242-NUC Compatible, Pack of 4 HEPA + 8 Carbon Booster Filters by Stanley Redline

I have already placed some orders so I can now give a review. I have two cats so these filters are a must for me. HEPA filters last about three months. Since they come with multiple charcoal filters, I use them as a pre-filter and they last about a month. I simply place the charcoal filter in front of the HEPA filter and the front cover of the unit holds it in place. I threw away the thin foam pre-filter that came with the unit because I don't want to clean it. This scheme suits me very well, I will continue to buy them.
