Alen® air purifiers are engineered to outperform by combining power with efficacy and superb filtration technology. And our beautifully designed, whisper-quiet units do it without disrupting your conversations or your lifestyle. We don’t all know how loud decibels are and what some people consider loud, others may not. That’s lasko pedestal fans why we take videos of all the air purifiers we review, recording each unit at their different fan speeds. Both units come with an AQI (Air Quality Indicator) color wheel in the center of the control panel. Using data provided by the air purifier sensors, this light displays the air quality in your room using five colors.
✅ If you want to pay a little extra for features like an auto mode and the choice of ionization — go for the BreatheSmart 45i. Replacing your filter periodically ensures you’ll have plenty of room to trap those harmful contaminants from the air in your home. As the 45i and Flex are the same size, Alen decided they could use the same filters for both. First, we bought the BretheSmart 75i, which showed us how powerful Alen units can be.
This unbeatable combination allows for whisper quiet removal of particulate matter, even on the highest setting, 24/7. The biggest difference between the features on the 45i and Flex is that the 45i comes with an auto mode. This uses the same air quality information from its sensor to adjunct the fan to suit the amount of pollutants in the air. The cost of replacement filters is the true cost of any air purifier. Some companies do have a ridiculously low price of the air purifier itself because they earn money on the replacement filters. This indicates at what fan speed setting you should run the Classic large air purifier.
Alen® 45i Air Purifier’s powerful, high-speed fans continuously move air through True HEPA 13, medical grade filters to produce ideal conditions for better sleep. Experience non-stop protection from irritants that can affect sleep quality with our beautiful, quiet, best-selling, bedroom buddy. The Alen® FLEX is the ultimate purifier for the kid’s room, guest room, home office or home gym.
Keeping your pre-filter clean will extend the life of your air filter and keep your purifier working at peak efficiency. Pre-filters can be removed and cleaned by vacuuming, but some customers prefer to discard their heavily soiled pre-filter and exchange it for a fresh one. This pre-filter is intended only for the BreatheSmart 45i or the BreatheSmart FLEX.
Predicted brand reliability ratings are based on estimated problem rates for newly purchased room air purifiers, by the end of the 5th year of ownership. The app is designed to manage mulitple purifiers but lets you control and drill into data from individual units. To recap our previous review, the 75i is a True HEPA Air Purifier designed for residential or commercial use. The latter seems a more likely scenario given the appliance’s 27 x 19 x 12-inch (HxWxD) measurements and its ability to service rooms up to 1,300 square feet. A pair of wheels on the rear make moving the 27-pound unit slightly less cumbersome.
This shows that the Flex is working harder overall as it has a lower CADR of 225 CFM compared to the 45i, which has 245 CFM. Seven touch-sensitive round buttons are placed along the black glossy top of the 45i to adjust its settings. When it comes to the design aesthetics, it’s a draw as these two both look virtually identical. Let’s do a simple calculation to figure out how much electricity will the Classic model need.
