One HEPA Replacement Filter Pack

Edit: I've had my entire Honeywell HPA 100 for a year and a half. I've been using these filters for it since about 4 months in (so for about a year). Originally, I lived in a house with two cats that I was allergic to, so it was a very necessary purchase. And it did make the air in my bedroom better so I could sleep better. The filter that came with the air purifier got clogged quickly because we were doing some drywall work and there was a lot of dust it cleaned out of the air. It made sense that it got clogged up and NOISY so fast. Noisy like the sound of an ice machine running-unevenly loud and thus hard to sleep through if you run it at night like I do. I couldn't and neither could my wife, who is a much heavier sleeper than me. But every single filter from this package that I've gotten hasn't lasted any longer, and it's disappointing. About 4 months ago I moved into my own place with no cats. And also a place without forced air heating/cooling. So I should have less gunk in the air. But ever since I got the air purifier, the HEPA filters, which say they should last 1 year, only last about 3-4 months before they get LOUD in the same annoying way. The price is great,and they do definitely work well!, but not when you're buying it every 6 months instead of every year. I don't know if this is an issue with all HEPA filters, or just these ones, but it is disappointing. I'll try something else out next time and see if it does any better. Original Review: These are perfect replacements for my Honeywell's HPA-100 air purifier's filters. They fit exactly, both the pre-cut carbon filter and the True HEPA filter. For $35, it's hard to find a way to beat that for two True HEPA filters and 8 carbon filters. I'll definitely be using them again in the future when I need more! There was no smell with these at all. The carbon filters came in their own bag for all 8 and the HEPA filters each came in their own bag. Each of the HEPA filters had the little tabs on the one side so they'd be easy to pull out when you remove them. Great buy!
