If you have more than one pet or suffer from allergies or respiratory problems, you should change the filter once a month. Most effective purifiers include HEPA and activated carbon filter combinations. The Alen BreatheSmart 75i uses this filtering combination to remove harmful pollutants as well as harmful particles.
The 75i is suitable for up to 1300 ft² (121 m²), the highest among all Alen air purifiers. In both cases, the numbers were based on an assumed two air changes per hour (ACH). You will only need to replace your Alen filter once every 12 to 15 months. For one, the air intakes are positioned on the side with the exhaust on the top, so the unit can be placed against the wall to save space.
Speaking of features, one of the things I love about this model is it produces something called Pink noise. BreateSmart 75i’s much improved, the better-looking control panel is on the top of the unit while there are intakes on both sides and the bottom of the system. There are some other things you can do to help extend the life of your Alen BreatheSmart 75i. One of them is performing regular maintenance on your home’s HVAC system. Have it professionally serviced every year by a certified company. Your cooling system should be checked in the spring and your heating system should be checked in the fall.
There are also models that can ionize incoming particles, which are then sucked in by metal plates or other treated substances. I loved the Breathesmart classic air purifier because it has a great design and gives you lots of customization options. Most people don’t like big ugly boxes in their room, clashing with their decor. You can buy interchangeable front faceplates in fourteen colors.
However, a stand-alone air quality monitor is a great way to see where another home air purifier unit would be helpful. To have the air in your home Lasko Box Fan fully treated, you would need an air purifier in every room of the house. Most people don’t have the money to be able to afford that, however.
