PuroAir Air Purifier

Overpriced for performance though company is easy to work with: I almost never leave full detailed reviews but I found this to be worth some time given the marketing and real-world usage concerns. First, the bad: They are $100 per unit over competing brands and clean about 1/2 as much. I have 2 units in a room that gets toasty with west facing windows in the afternoon and they replaced 1 unit I had in there otherwise. Given the heat and building's lack of HVAC I needed something I could count on in the space - the price was appealing considering you get 2 units but unfortunately the claims of how much they clean the air and in what space is WAY overstated. They are working together in a 300sq ft room and the eTVOC (as unreliable as those sensors can be) are consistently 100-200ppb over what the other 1 unit could clear in the mid afternoon when off gassing really becomes an issue from building materials.. Also, the PM2.5 and PM10, while it is perfectly in acceptable limits, is usually 2-3 counts higher than with the other 1 unit. Again, that's with 2 units in the smaller space against 1 other of another brand which is commonly on sale for more than $100 less per unit. Also, CO2 stays a bit higher with these units, while that is typically an airflow problem, my suspicion is the underpowered fans. Simply, the carbon beds are too light, there is no carbon pre filter (though seems to be inserts to put in your own), and the fan is underpowered to be able to actually pull off the clean that is advertised. Some fair spots: They do clean the air - over ambient with them off the air is cleaner. They just perform much worse than other brands which sale for considerably less. But, if you don't have a room that necessitates needing real cleaning, they'll take out some VOCs and some PM - just don't expect them to perform up to their price point. The good: I ordered the pair and one arrived damaged. The motor had completely fallen on the inside and the brackets/vents were shattered upon arrival. The company promptly sent out a replacement unit with only needing pictures to verify the damage.
