If you are looking for a quality purifier with more power to clean a large space in less time, we recommend the Okaysou AirMax 10L. Generally, the HEPA filters need to be changed out more often than the carbon and macro filters. Moreover, in a multi-layer setup, the outermost filter is often washable and reusable, which means it rarely needs to be replaced. Even at its highest setting, this Alen purifier uses only about 45 watts of energy. As their website points out, this is less than the power used by a lightbulb. If you plan to keep your purifier running consistently, energy efficiency is an important factor to consider.
Moreover, the air flow system concept has changed, to a common bottom-to-top. With a big air intake grill behind the panel, the lasko pedestal fans FLEX draws in polluted air, purifies it and releases back through the top air vent. A typical air flow concept which are used widely in price range of $300 to $400, from Blueair Classic 205 to Rabbit Air BioGS 2.0 and GermGuardian AC9200WCA.

This one has a low energy consumption of only 8 watts on the lowest speed and 48 watts on the highest. If you’re in a household that’s trying to save up on electricity so badly, this would be a good addition to your appliances.
The second thing that stands out about this air purifier is how simple and intuitive it is to use. Alen has thoughtfully designed the BreatheSmart so anyone can use it, featuring large, clearly labeled controls – no tricky little buttons or confusing, overly-engineered controls. Its simplicity is perfectly complimented with smart sensors and indicator lights adding to its ease of use. Lastly, its quiet “pink noise” sound level on speeds 1-3 is quite impressive, especially for its size. Its pleasant sound level and ability to turn off all illuminated controls/indicators makes it a great choice for bedroom use. Since it has an RFID chip for the Smart Filter, it is easy to tell when you need to replace it to save you trouble in having to disassemble the unit now and then.
Many other air purifiers have some features that make them stand out on the market. Still, Blueair 211+ and Alen FLEX bring the game to a higher level. As you can see, lasko pedestal fans there is not much of a difference between the two air purifiers, in terms of wattage. The operating power is 61W in the case of Blueair 211+, while 50W in Alen FLEX.
But, this doesn’t end the story about the Alen FLEX filtration system. The producer offers you a multiple carbon filters option. In this review, I’ve used a carbon filter with 0.66 lbs of carbon but Alen FLEX can even offer you a filter with 2 lbs of carbon.
