Have had much fewer problems with allergies since I started using it. Air Purifier - 08/09/2012 We are very satisfied with the air purifier from Honeywell. Shipping was very quick, the purifier arrived with no damages.

It runs just as described, very quiet & seems to be purifying the air in our home. Very happy with the purchase! Reviewer: Charles Ted LINCOLN I have had this product for a full week - basically it is working fine E X E C E P T for a constant click that sound when the oscillating feature is on - it makes this sound on what I guess is either the first turn or the return turn sequence - I first noticed this when I was woken up in the middle of the night when the oscillating feature was ON. WHY does this occur, whould be my inquiry?!?I read somewhere that once this unit is on, you cant smell ANYTHING in the room. I found that hard to believe, but once I got this going in our musty basement, the next day it was truly odorless! Ive since recommended this to family and Im installing them at my work. I just wish that Honeywell had more faith in the product and marketed it more, as its tough to find in retail locations.

, but not the rest of us)Appears to have a poor build quality compared to other Honeywell purifiersUntil acquired by Allied Signal, Honeywell was a home-town company for me, so I really wanted to see this product live up to its brand name; unfortunately, that didn't happen.I purchased this item to replace the discontinued Hamilton Beach 04163, for which parts are becoming scarce. I have friends who own the Honeywell 50250 and swear by it, so I was happy to find a Honeywell model with most of the features I wanted at a price I could afford.I ended up sending this item back and ordering a different brand for two main reasons:1. Although not noted in any of the advertising, I had hoped for the price the item would have an air quality sensor that automatically adjusts fan speed accordingly when it senses particles or odors. I paid less than $150 for the Hamilton Beach 04163 and in addition to the same three types of filtration, the Hamilton Beach also had an LCD that visually displayed air quality and an automatic mode to increase fan speed temporarily when the unit sensed increased particles or odors.

Having a "set it and forget it" feature on an air purifier is like having a car with heated seats during the winter; if you've never had the feature it doesn't seem worth the money, but once you've used the feature you wonder how you ever lived without it.2. My unit came broken out of the box; from the minute it was plugged in, the motor would "sag and surge" once every few minutes as if a high wattage appliance had just been turned on. In addition, the unit produced a very high level of electrical noise. At first I assumed both these problems may have been caused by outdated wiring, so I plugged the unit into my sensitive electronics surge protector, which in addition to protecting from power spikes and surges, includes a line conditioner to make sure devices are receiving a consistent and proper amount of power; this did not correct either problem. I also experienced the "plastic smell" noted by other reviewers.One good thing I didn't notice that other reviewers complained about was noise.

In fact, because of so many noise complaints on almost every brand of air purifier, I decided to unscientifically compare sound levels by installing a Volume Unit Meter app on my iPad. With the units turned off, the app registered a baseline room volume of 39 decibels. On its lowest speed the Honeywell unit only produced 51 decibels as compared to the Hamilton Beach at 60 decibels on its lowest "Whisper Clean" speed. At the highest levels, the Honeywell unit produced 70 decibels while the Hamilton Beach was slightly louder at 72 decibels. Unfortunately, I found the Honeywell unit's high level of electrical noise to be so annoying on the lowest speed, that during its two days of operation I kept it at speed level six out of twelve, which matched the white noise created by the Hamilton Beach at its "Whisper Clean" speed.It should also be noted that in order for any air purifier to circulate air it needs some sort of fan or blower, and as with a typical household furnace, the more air the fan or blower circulates, the more white noise it produces.

I have to assume most noise complaints on all brands of air purifiers aren't due to the noise, but rather to the promises of quiet that never comes true; as in the case of the Hamilton Beach's 60 decibel "Whisper Clean". Sixty decibels is by no means close to the actual sound level of a whisper. Unfortunately this is how products are currently allowed to be marketed; at least in the United States. The only truly quiet air purifier is the one that is broken or turned off.One bad thing that I didn't see other reviewers comment on was the air circulation pattern. As noted in my list of cons, the Honeywell unit circulates cleaned air around the floor and not much higher. This is by no means the fault of the Honeywell unit; this fault can be attributed to the "tower" design itself. Although not nearly as attractive, the "box" design is much more effective at circulating air to levels where people actually breathe at than tower units are. Personally, I'll take the function of an ugly box unit that intakes dirty air from a low level and expels cleaned air at a higher level any day of the week over the stylish form of a tower unit that both takes air in from and releases it near the floor.

I case you're wondering, I decided to go with the Rabbit Air BioGS (model 421A - covers 600 sq. ft.) High Quality Ultra-Quiet Air Purifier - Low Maintenance - Washable Filters!; although approximately $130 more than the Honeywell unit, it has my "must have" air quality sensor with automatic odor and particle response, as well as more levels of filtration. It's also a box unit I find more stylish than the plastic finish Honeywell unit. To make up for the lack of a UV bulb, I spent $50 and also bought a Germ Guardian GG-1000 UV-C Air Sanitizer, which I plan to plugin next to the Rabbit Air in order to take advantage of its more powerful circulation.For those looking to stay around or below the $200 range, I would look at the Winix PlasmaWave 5300 Air Cleaner Model, which for $50 less than the Honeywell unit has the automatic air quality adjustment I've come to love and highly recommend. I also recommend doing more research. the author gives the most meticulous reviews of all types of air purifiers.
