Filter-MonsterReplacement HEPA Air Filter - Compatible with IQAir HealthPro Series V5-Cell Gas & Odor Filter

This filter seems to be a good value as opposed to the OEM filter. It took me a while to install it, but that was on me. For some reason I was trying to put it in upside down. Once I figured that out, it slid right into place. It does not seem to be quite as well made as the original, but I don't think that will have any effect on the way it works, and since it just sits inside of the air filter, it doesn't get wear and tear, so it should be fine. I would buy again, definitely. I've had it for several months now.

Had to remove immediately after installation due to terrible smell filtering through the room.

In the past I’ve always used the IQAir OEM filters in my Healthpro Plus but decided to try another mostly due to price and now additional shipping charges. The filter fit perfectly but was fairly distorted and not as rigid as the OEM activated charcoal filter. Coincidentally I had also purchased a air monitoring device several months previous and had about 90 days of results of PM 2.5 as well as tVOC amounts. With several months of running my IQAir Healthpro Plus the tVOC measurements were in the range of 1.3 to 1.6 mg/m3 or in the range of slightly high. The IQAir filter was well within the range of good use, about halfway through its useful life. I have my house professionally cleaned by a cleaning service every two weeks for the past four years so the environment remains fairly stable or as stable as it can be in a non laboratory environment. Plus the Healthpro plus runs 24/7. After several days of using the Filter Monster the tVOC measurement fell to .28 to .35 mg/m3 and has stayed consistently between those two measures! So the tVOC fell from slightly high to between excellent and good! To me that was an amazing result! Outcome is I’m going to use Filter Monster from now on for the activated charcoal filter and I would recommend this to other Healthpro users!

Easy to install and affordable price.

The first one I received had a smell kind of like burnt wood... which is understandable, but not acceptable. I contacted the seller and they sent me a replacement asap. The replacement didn't have the odd smell and has been working great.
