The Honeywell 50250-S is best used in small spaces, and does a good job of removing dust and other allergens from the air. The biggest complaint surrounding this unit is that it's noisy, noticeable even at low speeds. A near identical version, the Honeywell 50250-N, is said to have permanent filters, but that's more marketing than reality as its filters, too, need to be replaced. That matters little as the filters in both models last a long time and are relatively cheap.
Good for small rooms. The Honeywell 50250-S is best used in small rooms as it's not powerful enough to clean rooms with larger capacity. The Honeywell air purifier takes in air from all sides of its cylindrical design, expelling clean air out the top, but it doesn't pull as much air through its HEPA filter as more expensive models, such as the Blueair 503, experts say. Still, notes Ed Sherbenou of Air-Purifier-Power.com, this air cleaner offers "a lot of power for the money." Testers from one professional consumer testing organization say the Honeywell 50250 is excellent at removing dust, pollen and cigarette smoke at its high setting, and also does a good job at the low setting.
Easy use with filter indicator lights. Filter indicator lights let users know when it's time to change out -- or at least vacuum -- the filter for maximum performance. The unit itself is fairly large, according to Sherbenou, and it needs to sit a minimum of three feet away from a wall. Therefore, it will take up some available space in the room. It's lightweight (just 20 pounds) and has a carrying handle at the top for easy transfer from room to room. Replacement filters are easy to find online or in stores.
Noticeable noise on low, quite loud on high. Sherbenou praises the Honeywell's cleaning power, but says he rarely will use it in his bedroom because of the noise. One professional testing organization gives the Honeywell 50250 a rating of Poor for its noise level at the highest fan speed setting, and a slightly better rating of Good for noise at the lower speed settings.
Affordable filters, low up-front cost. The Honeywell's long-lasting HEPA filter should be vacuumed twice a year, but Sherbenou says it will eventually have to be replaced. The Honeywell also uses an odor-reducing carbon prefilter (Est. $15) that should be replaced every three months. It's not Energy Star qualified, but power draw isn't terrible -- about as much as two standard light bulbs, Sherbenou says.

Air-purifier expert Ed Sherbenou owns a Honeywell 50250, and it shows in this illustrated review. He says the 50250 is well sealed and has a big filter. "I have seen 18-wheelers with smaller air filters than this," he notes. But it's so loud that he doesn't use it in his bedroom.
