Filtering System That You Need

Alen BreathSmart FIT50 has a different filtration system; it all depends on the type of filter you are using. If you buy FIT50, then you are probably using HEPA Pure filtration system, because extra filters need to be ordered separately.

HEPA Pure Filtration System

This filtration system is basic, and most models come with that filter. HEPA pure is good to remove allergens like pollen, pet dander, dust, mold spores. If you have allergy troubles, then this filter is recommended. 

Inside the HEPA Pure filtration system is pre-filter, which the primary purpose is to hold big particles getting to the layered multiple HEPA Pure filter. HEPA Pure is the base model, and all other filters that you can buy as an extra option include HEPA Pure filter.

HEPA Silver

It has HEPA Pure filter like already mentioned above. But after a pre-filter, air goes through silver filter which is specialized to trap bacteria, mold spore and maybe even some viruses. After a HEPA Pure filter is carbon layer which is good to remove bad odor, chemicals, and gases from the air, including smoke.

HEPA Fresh Plus

HEPA Fresh Plus is made for a home that needs extra freshness. This model has pre-filter, HEPA Pure filter as well as Activated carbon layered filter that is on its own good at keeping the room fresh. However, in this model, Alen BreathSmart added an extra HEPA Fresh Plus filter that works amazingly at removing kitchen odor, VOCs, gases, smoke and other fumes from the air. 

HEPA Odorcell

This filter model is made for people with pets, nursery room, or any other stinky room. We all know how smelly can it be when a baby poops, and you need to clean her in a nursery room. Now with this filter model nursery room will be fresh as it is new.

If needed, you can turn on the ionizer. The ionization process is on a bad reputation because low-quality air purifiers were emitting harmful components like ozone. However, Alen BreathSmart FIT50 is not such a model. This is a high-end air purifier which will not emit any harmful ozone at any time. It is perfectly safe top use ionizer included in FIT50.

Speed is also adjustable, and you can choose from four speeds. The lowest speed is ideal for sleeping and bedroom. At low-speed, Alen BreathSmart FIT50 won’t make any noise that will disturb your sleep. 

In case you need to filter the dirty air fast you can choose turbo speed. Around power on button is air quality indicator which moves from red to blue color. Red being bad air indicator and blue is an indicator for clean air. All the options on the top panel can be locked in case you have a child that likes to push buttons. Also, if all these options just confuse you, you can always use auto mode and let Alen BreathSmart uses its advanced sensors to monitor air and adjust the settings to the air quality in the room.
