If you are looking for a high quality air purifier at a reasonable price (around $150 dollars), then the Honeywell HFD-120-Q is a great option. Its really quiet, has washable filters (which is a huge convenience and saves money) and has a built in ionizer that delivers extra cleaning power to filter the air in your room about every 12 minutes. The purifier’s True HEPA filter says that it removes 99.97 percent of all airborne particles that pass through, such as pollen, cat dander, household dust, tobacco smoke, and mold spores. There is also an electronic filter check indicator telling you when the filter needs to be cleaned. We have been using this in our bedroom and don’t even notice that it’s on, but when I went to clean the filter, I could see that it’s working. My only complaint is that the fan is pretty strong so that it can move around the air and the in winter that can create a bit of a draft in your room if its pointed anywhere near your bed.
The Honeywell HFD-120 has a sleek tower design and comes in black or silver. The oscillating fan moves around at 3 different speeds which you can control. The recommended room size is about 170 sq ft and the product comes with a 5 year limited warranty. This is the second Honeywell product I have tired out recently and I have been impressed with the design and ease of use.
