Holmes Group HAP242B-U HEPA Desktop Air Purifier Review

This desktop air purifier is a unique device that every office should have. Not only your air will be clean, but your customers will have a feeling like they have come in a very clean office. And you know that sometimes on hot days sweat can spread through the room and then bad smell can turn people away from you. Because of this bizarre problem, you may be losing clients. With this small but yet strong air purifier, you can remove these unpleasant situations from your working place.

Cute Design That Fits Every Desktop

HAP242B-U is small in size, and it looks like a little radio. If you say nothing about it, people will think it is a desktop radio. You can place it in two positions, one is to lay it down and place it horizontally, but if there is not much room on the desktop you can also put it in the vertical position. In both positions, Holmes air purifier will work great. My favorite color is black as it looks more like a modern device. If you don’t like the black color, you can also get this amazing air purifier in white color. The white color is not attractive like the black color, and it is usually sold for the affordable price than the black colored HAP242B-U.

HEPA Filter

Holmes put HEPA type filter into this air purifier. This filter guarantees that 99% of all particles in the air will be removed. The air purifier will remove everything bigger than 2 microns from the air. HEPA filter is the core filter in every air purifier.

Aer1 Filter

For removing odor and smoke Holmes integrated Aer1 filter. Aer1 filter is used in many other air purifiers that Holmes produce. You can also enhance your Aer1 filter with baking soda, and this way remove smoke and bad smells from the room. This filter can be replaced at low cost just like HEPA filter.


HAP242 has an optional ionizer. Ionizers are extremely useful at removing bad smells from the room. But they are having a bad reputation because they produce ozone. High ozone level is harmful to humans. Because of that, you should not be in the room that has ionizer turned on. Once the ionizer is done, you can open the windows and let the ozone go out. And your room will be fresh clean.

3 Speed Feature

All this air purification can be done in silent operating mode because HAP242 is working quietly. Thanks to the three-speed features you can speed it up, but then it may not be so quiet.
