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.
We then turn the air purifier on at full fan speed to see how long it takes them to remove all the contaminants from the room. Sometimes, you’ll find that air purifiers with touch-sensitive controls are lacking on the “sensitive” part, making them hard to operate. From the units we’ve reviewed, we found the controls very easy to press, and little force is needed to activate them.
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.
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.
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.
