Blueair 203W HepaSilent Air-Purification System, White

Back to Buy Another One
After allergies triggered asthma for me, I could no longer get by with a cheap air purifier. I researched for hours before deciding on this one. I was looking for something that I could use in the bedroom to help me sleep. This fit the bill on all fronts.

Not only does it clean the air, but produces white noise which helps block out the noise of your neighbors. I will advise, it is quite loud on the medium and high settings, but produces great airflow if you have lower ceilings. You won't even need a ceiling fan with this turned on high.

Upon first use, it smelled, as is common with a new HEPA filter. This disappeared after a day. Within two days, the air was so clean, it was noticeable just by taking a deep breath. Nearly two weeks later and the room still doesn't need to be dusted. This will cut my cleaning frequency down tremendously which is a good thing for my lungs.

The most obvious sign to me that this was a good air purifier was after one week...

Not silent, but soothing sound and compact size compared to other models
Although this unit is not quite as quiet as the 400 series Blueair, the 400 series is quite a bit larger and looks like a big huge computer tower. The 200 series is a nicer size and looks more like an air purifier. The sound from the 200 series can actually be quite soothing in terms of helping you to sleep and relax. In my fairly small bedroom, both units seemed to perform equally so I opted for the 203W since it looks better, was cheaper and the filters are a bit cheaper as well.

The Blueair 203 includes an electronic filter change timer as well.

I recommend this unit for the price-the air seems a whole lot fresher and cleaner and my allergies have been alleviated.

I do wish it had one lower setting that was slightly quieter though the lowest setting is by no means loud and most people would not even notice it at all if you had it on in a room and the unit was out of sigh or something like that.

I bought it about a month ago to aid the allergy treatment of our toddler. The unit was delivered on time and was very well packaged. It came with one HEPA filter, a "days to filter change" display counter to remind changing the particle filter every 6 months --an explicit requirement to preserve the unit's warranty, see below--, and some printed material (user guide, warranty, and a pitch to join a Blueair filter Club).

The dimension specs given in the webpage are true. It is a steel-sheet cabinet, whose size (comparable to that of a bulky floor-standing PC) adds to the look of being solidly built; its weight is easily managed by an adult. The unit operation is controlled by a mechanical rotary switch (off, low, medium, high) ; it is remarkably quiet at the lowest speed, which is labeled as 'HEPA silent' on the rotary knob markings. A blue LED on the front signals when the unit is on, with a measured illuminance of 2.7 lux. Although under daytime (photopic) vision such...
