Welcome to the quick guide on the best attic air purifiers and where to place them! Here are my reasons why I have picked HoMedics TotalClean 5-in-1 Deluxe, Blueair Blue Pure 211+ Auto and Winix PlasmaWave A230 as the best air purifiers for loft:

  • High CADR, meaning high airflow and good air circulation that results in better removal of airborne contaminants and odors;
  • Auto function to save up electricity if the air is clean;
  • These air purifiers are portable and are ready to use out-of-the-box;
  • Noise levels don’t matter much;
  • 360-degree filtration to cover the whole attic area;
  • All of them are HEPA air purifiers.

Now let’s quickly sum up which air purifier you should get for your attic.

HoMedics TotalClean 5-in-1 Deluxe with its UV-lights and ionizer is an all-around option for people who want to keep their attic clean from dust, bacteria, mold, fungi and viruses. UV-bulb has to be replaced every 12 months, however, they are super cheap – buy a pack of two lamps here. The HEPA filter (includes pre-filter and Carbon filter as well) also has a lifespan of 12 months. Overall, for 300 – 400 square feet attics the HoMedics TotalClean 5-in-1 Deluxe is the best pick.

Blueair Blue Pure 211+ Auto has a higher Clean Air Delivery Rate (it’s also AHAM-verified) for smoke, pollen and dust particles. Allergens and odors get caught quickly by the large Blueair air filter (HEPA, Carbon) thanks to the powerful motor that is able to generate high airflow and get the air from the furthest of places. In general, this is one of the best Blueair-made air purifiers for large rooms, including large and extra-large attics.

Winix PlasmaWave A230 is the best option if your attic is small and viruses do not bother you that much. It’s also the cheapest air purifier made by Winix.


Can any of the listed air purifiers remove the musty smell?

To remove the musty smell an air purifier must meet two conditions:

  1. Be able to cover the entire area;
  2. Has to employ a high-quality Activated Carbon filter.

By all accounts, the Blueair Blue Pure 211+ Auto is the best option here.

Where to place a loft air purifier?

I place my air purifier in the center of my attic, so it is equidistant to all corners and covers the entire area.

How do air purifiers help with attic ventilation?

Air purifiers are designed to remove toxins, allergens, dust and other irritants from the air, to help people with allergies and improve air quality in general. But they cannot replace the proper attic ventilation in any way.
