Put the FLEX to work cleaning up to 700 square feet of air every 30 minutes. Add a customizable filter for your specific needs in each space, and you’ve got pure air, everywhere. We’ve calculated this using the B4-Fresh filter, which we recommend for most household pollutants.
Lasko Box Fan Classic was created as a large bedroom air purifier. It should be quiet as a mouse; high noise levels and sleeping don’t go well together. CADR scale goes from 0 to 450, with an approximated 200 average for a standard air purifier. In short, they are brilliant even at removing the smallest air particulates such as small dust particles, smoke particles, pollen, mold, mold spores, certain bacteria, and so on. Only Alen combines advanced filtration technology with increased motor power for maximum airflow and minimal noise.
Dust, pollen, smoke removal is how well a model cleared air of fine clay dust and cigarette smoke when operating at a low speed that was typically one setting above the lowest speed. Many models have multiple speeds and the lowest is not as effective at cleaning the air. A model that scores well for dust removal should perform comparably for pollen. The Alen® 75i Air Purifier isn’t just a game changer—it’s a life changer. Consumer Reports recommends the Alen® BreatheSmart 75i Pure with an overall EXCELLENT score.
The more activated carbon a filter contains, the more contaminants it can remove. The 45i is lighter, so it is easier to move, but they both feature a flat, removable front panel held on with magnets, curved edges and measure up the same size. To the untrained eye, you would never be able to tell the difference. We try to keep up with sales for every air purifier we review; Alen BreatheSmart Classic sales included. While the new flagship 45i and 75i models achieved the super quiet operation (below 50 dB), the Classic doesn’t share the same noise profile.
Owner satisfaction ratings are based on the proportion of members who are extremely likely to recommend their room air purifier brand to their friends and family. We’ve added this extra decibel to the Flex, working a little harder to match the 45i’s cleaning performance. With the exception of their basic B4-Pure filter, they contain various levels of activated carbon pellets. This is used in filters because of its ability to adsorb odors and other VOCs (Volatile Organic compounds).
