I don't know about you guys, but my allergies have been kicking into high gear the last week or so here in Oklahoma. While a HEPA-certified air purifier like the Coway AP-1512HH Mighty won't prevent allergens from being in your home, it'll sure curb their presence to a degree.

This box fan-sized purifier uses a four-stage filtration system (pre-filter → charcoal filter → HEPA filter → ionizer) to clean areas up to 350 square feet — about the size of a typical living room. The filters only have to be replaced about once a year, although the pre-filter may need monthly cleaning depending on how much hair and whatnot it picks up.

The device has six modes:

1. Auto — adjusts airflow speed on the fly based on air quality
2. 1/Low — silent operation
3. 2/Medium — barely audible
4. 3/High — relatively loud
5. ECO — shuts fan off after 30 minutes if no debris/dust/etc is detected, saving on energy consumption
6. Ionizer — freshens the air; can be toggled on/off independently of other modes

A color indicator on top lights up to tell you about the room's air quality. Blue = clean, purple = medium pollution, and red = high pollution.

Get the Coway AP-1512HH Mighty air purifier for $200 on Amazon.
