Holmes Products HAP242-UC Air Purifier
The HAP242-UC air purifier by Holmes can be placed vertically or horizontally to help save space, which is especially handy when using it on a desk or tabletop. The HAP242-UC uses a HEPA-type filter to effectively remove up to 99 percent of pollutants and allergens commonly found in the air, while a carbon filter and optional ionizer remove odors and further freshen output.
This air purifier is effective in rooms up to 109 square feet in size, while being quiet enough on its low setting to be used in a bedroom overnight. The HAP242-UC does require replacing the filter periodically, but the process is simple and replacement filters are easy to find. Overall, this effective and compact air purifier offers excellent performance for the price.
