Rating: - Hepa Filters - necessary evil
If you purchase an air purifier, you will, no doubt also have to replace Hepa Filters every so often. They are not inexpensive, so you will need to search for the best price. This particular filter for the Holmes Air Purifier, is very easy to access and replace. It is supposed to last for one year, however, will probably depend on how much particulate matter it has to deal with. I replaced my 3 after 3 months. Hopefully, the next group will last longer.

The holmes filters are great. They last a long time considering i leave it running 24x7. Easy to replace.
