While the odor from the burnt paper wasn’t entirely eliminated, it was severely reduced. Our performance testing consisted of a few different components. The first was making sure that the CADR number provided by the manufacturer was verified by AHAM . This ensures that the machine’s efficacy has been verified by a third party; not all air purifiers go through this outside verification. The BreatheSmart 75i has the AHAM stamp of approval and is capable of cleaning 400 cubic feet of air per minute. Ultimately, this means that this is an exceptional option for large rooms.
And during the COVID pandemic, Alen has donated air purifiers to hospitals and schools and helped get businesses and state governments safely back to work. Even at the lowest Speed 1, the Classic generates 45 dB of noise. This is quite a lot; comparatively, as we have discussed in the 75i review, that air purifier generates only 25 dB at Speed 1. As previously stated, the Classic model is the largest air purifier from the original line of Alen BreatheSmart units. Rated one of America’s best large room purifiers year after year, the Classic is perfectly sized for large rooms or open plan living spaces.
As mentioned you get a bunch of color options with optional faceplates. The streamlined shape almost makes it look like art rather than a cold and sterile appliance. I can tell you from experience that you just don’t see many air purifiers that look half as cool. If you want a device that’s a bit smaller, you should also read our review of the Atmotube portable air pollution monitor. However, at the highest speed – Turbo Speed – it consumes 105W of energy. It is a large room air purifier, larger air consumption is expected, but the Classic model does drain more energy than comparable energy-efficient large room air purifiers.
And thanks to its auto mode, if it doesn’t sense any pollution for 30 minutes, the fan will automatically stop to conserve energy. While this air purifier was designed for use in the bedroom , it’s quite portable and can be moved from room to room if needed. Aesthetically, it wouldn’t be out of place on your nightstand with its white or black case and sleek design. Though its capacity is on the smaller side and it doesn’t have as many features as other air purifiers on this list, it’s hard to beat the price. That said, if you want a little more square footage, the brand’s Core 300 model works in rooms up to 219 square feet, and retails for around $100. The Alen BreatheSmart Classic’s big draw is its amazing room coverage of 1,100 square feet.
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. When the alen breathesmart air exchanges per hour drop to a certain point, you won’t be receiving all of the benefits of allergen-free, breathable air. For optimal performance, a good rule of thumb is to find an air purifier that can cover more than the square footage of your room.
Testing performed by our experts shows air quality decreases significantly after only two hours of turning off your air purifier. We recommend running your air purifier 24/7 to maintain the purest air possible. Filter changes are needed every 6 months when following this recommendation. On top of that, Alen is the first air purifier brand to introduce a lifetime warranty. By buying the lasko pedestal fans Classic, you’re playing it safe; the warranty covers all the problems you may have.
Many people even commented on their new purifier’s sleek design and stylishness. Beyond these groups of people, the Alen air purifier line of products is also an excellent option for people on a tighter budget. They pair quality with affordability as much as possible with their air purifying products.
As the decisive criteria for the performance of one air purifier, by default we look at the quantity and the quality of its air filters, and what the air filter types are using. The Alen BreatheSmart starts with the unique Alen’s 3-stage air cleaning system. At the center of this air cleaning system, you can choose 1 from 4 different level of HEPA air filter as below. For those looking for a versatile and powerful purifier for under $450.00, you would be well served with the Alen Breathesmart 45i. The Medify MA-40 Air Purifier is a great option for people who are looking for an affordable way to improve their indoor air quality. This purifier is designed to remove pollen, dust, smoke, and other particles from the air, and it comes with a built-in filter that captures 99% of all pollutants.
