And when harmful particles are detected, Auto-mode can automatically adjust purifying power to keep your air pure 24/7. The efficacy of an air purifier is typically measured in air exchanges per hour, or how many times within an hour the air in a room is completely replaced. A rate of six exchanges per hour or more is considered very good and would meet our standards. If your square footage exceeds the listed square footage for your air purifier, it can still clean your room, but the rate at which it can do so decreases.
150 CADR rating is a safe bet that an air purifier is actually a good purifier, not a mere air blower. The filter has to actually pick all those dust, smoke, mold, dander, and other particulates out of the air and deliver clean air back into the room. The CADR rating is probably the single most important air purifier specification.
This means you can see at a glance how well the BreatheSmart is purifying your air. The BreatheSmart is in about the same price bracket as the Dyson Pure Cool, but doesn’t have the in-depth feedback the Pure Cool can provide within the Dyson app. The Lasko Box Fan air purifier series is available in a number of popular models, including 45i, 75i, Classic, Flex, and FIT50. Each model’s specs are slightly different, so that you can find a purifier that’s both ideal to your square footage and other purification needs. The Breathesmart series also offers 4 different types of filters, each excelling in different areas including mold, chemicals, VOCs, smoking, cooking odors, and pets.
This is the largest version from the Breathesmart range, for it’s slightly smaller brother, check out our Alen Fit50 review. A. The alen breathesmart FLEX Air Purifier has 4 types of filters. The standard one has a foam-type pre-filter and a HEPA filter. The rest have a foam-type pre-filter and a composite filter (HEPA + odor).
If you want to protect you and your family from indoor air pollutants, we recommend the Alen BreatheSmart FLEX Air Purifier. Pink noise reduces jarring noises, which jolt you out of sleep. Such noises include a car horn honking, someone snoring or a door slamming. Thanks to the pink noise, you can fall asleep faster and have a deeper sleep longer. Activated carbon often re-release chemicals after adsorbing.
The brilliant engineering that went into the FLEX is obvious when you compare the CADR rating to FLEX’s max. Alen BreatheSmart FLEX has a maximal airflow of 187 CFM. This is one of the few air purifiers that can deliver a 225 CADR rating at below 200 CFM max. That’s really brilliant engineering; you will hardly find such CADR to airflow ratio even in the large room $800+ air purifiers. You should choose the FLEX filter based on your situation.
