Review on 🌈 Colorfullife 4 True HEPA + 8 Pre Filter: Compatible Replacement for Holmes AER1 Allergen Remover Filter - HAPF300AH-U4R, HAP242-NUC by Eric Hartman

So I'm buying this exact one for the second time. I still wonder a little if they are as good as a well known brand but honestly I think they are the same or at least very close, especially considering the savings it's worth. And for the people who say they don't fit, if it says they fit your model AND look like the filter that came with yours then it will fit perfectly. I have 2 Holmes cleaners, a large (needs 2 filters) and a small (1 filter) and they fit perfectly. The black pre-filters help extend the life of the white filter. Also for the people who say they don't fit, they are literally the SIZE of the main filter. The only problem I see is having to hold him when I put the cap/cap back on because there is nothing to hold. They are there, but you can glue them to the main filter for convenience. I love them and will continue to buy them. DO NOT buy the blue ones, they don't work as well.
