Online reviews for the Lasko Box Fan Classic average at around 4.5 out of 5. They praise its accurate Smart Sensor and reporting, saying they can see the air quality light change based on their activities. To begin with, we have Blueair 211+, a real deal of an air purifier.
If you run it for 12 hours every day at this speed, you’ll be paying 8 cents a day. This equates to around $30 annually, assuming that you pay 12 cents per kilowatt-hour of electricity. ACH refers to how many times an air purifier will exchange the air in the room per hour. The name HEPA (High-Efficiency Particulate Air) is used on filters that are capable of removing 99% of air pollutants 0.2 microns or larger. To be certified as True HEPA, the filter should be able to remove 99.97% of air contaminants down to 0.3 microns. The ideal spot to position an air purifier is at the center of the room- but this is usually not applicable in most typical household settings.
Once again, both producers run a different warranty policy. If you decide to buy the Blueair 211+, you will get a two-year warranty. But, if you purchase the Alen FLEX, you will Lasko Box Fan get up to lifetime warranty coverage. There are some terms and conditions that Alen requires you to fulfill, but you can complete all of that straight on their website.
Similar to most modern air purifiers, the Flex starts by sucking air through a vent at the bottom. Here, the air goes through a preliminary screen that filters some of the large air contaminants before reaching the HEPA filter. This pre-filter is removable and washable and practically prolongs the lifespan of the HEPA. Unfortunately the more I learn about Alen’s air purifiers, the more I found them to be untrustworthy and over priced.
The Alen BreatheSmart Home Air Purifier could be one of the best on paper, but how does it fare in real life? I recently spent a month testing this air purifier and I certainly wasn’t disappointed. It’s not a big clunky oversized unit like some of the other air purifiers on the market. Are you looking for protection from allergies or just need to freshen up the air? A quick look at the specs for the purifier should tell you what particles it can effectively remove from the air.
