don't spend money on an air purifier you may not need - air purifier for smoke

Consumer Reports have nothing to do with any advertisers on this website.
Indoor air can be two to five times as much as outdoor air, so in winter, when the cold weather makes us stay indoors with our windows closed, it makes sense to have a surge of interest in air purifiers.
But in the hot weather, it is very likely that we will be turned off because of the start of the air conditioner.
According to Gfk, a market research firm, more and more consumers are turning to air purifiers to purify the air.

Norman EdelmanD.
Professor of prevention and internal medicine at Stony Brook University in New York, agrees that keeping indoor air clean is the best strategy, but adds that it is difficult to exclude all allergens and particulate matter from the outside.
He said: "The data of the air purifier is not clear . "
"If used properly, they can reduce allergic symptoms moderately.
"Air purifiers are not cheap and can be expensive to operate as they usually move around --the-clock (See below).

Noise is important).
Blueair Blue Pure $211,250 is our best performance.
It is very good at removing fine clay dust and cigarette smoke from the air in low and high settings.
Models with good dust scores are also good at removing pollen, which is roughly the same size.
However, in our test, the blue air is quite noisy at a height (
A little less, it's low). That’s typical.
"We recommend buying a larger air purifier and running at a slower speed for the best and quietest results," Trezza said . ".
Like the other four air purifiers recommended by CR, Blueair is suitable for 350 to 650 square feet of space
A fairly large room.
We calculated the cost of running each model for one year and five years.
The energy cost per year is based on running the unit 24 hours a day.
Filter cost based on manufacturer's replacement proposal-
Carbon filters are usually once or twice a year, four times a year.
