Holmes Carbon HAPF60, Filter C, Black, 4 Pack

For the price I expected the filter set

Not the size of an AER-filter (as suggested by a picture) but a bit bigger - but it's easy to cut so it works perfectly. I have a Sunbeam air purifier with AER filters, and it is not meant to have an extra carbon filter, but it still works if you can manage to close the purifier :)

Replacement filters for my air purifier. They work well

These filters are great! I have an older Holmes HAP8615 and had some difficulty finding HEPA filters, and these carbon filters in stores anymore. Amazon came through having both, and at a decent cost too. Carbon filters need to be replaced much more often then HEPA filters do, every month or so. So a pack of four being only a little over a dollar a filter is a reasonable price in my book. I've seen them on other sites for up to $20 for a four pack, so I'm very happy that these are priced as they are. I have severe allergies, asthma, and live in an apartment where the previous occupant smoked so air purifiers are mandatory for me. I run them hard, 24/7 365. I normally change my carbon filters about ever 2-3 weeks, but I've also found that I can rinse them off with some cold water, let them dry, and then replace them in the purifier to make them last even longer without a problem. I highly recomend using a carbon filter with your HEPA filter as well, since they lengthen the lifespan of your HEPA filter, and those are a lot more expensive then carbon filters are! All in all these are good filters, at a great price!

I have several HEPA air purifiers in my home. They run 24/7/365. I used to buy these from a large retail store in my area. Sometimes they would have them and sometimes not which would put me into a treasure hunt mode of looking at other retailers. I finally was smart about it and looked on Amazon. YES! Not only can I simply click and order them but they are cheaper. They work great. They are the exact same thing I was paying more for and feeling frustrated at trying to find. I am so grateful to have these available and I have them delivered through Amazon subscription. It is an easy reminder to change them out when they arrive. If you replace them regularly your HEPA filter will last longer.
