Buying guides

Buying guides for an air purifier for 400 sq ft

1. Size

When shopping for an air purifier, size is one of the most important considerations. You need to make sure that the unit is powerful enough to purify the air in the room that you want to use it. For a 400 sq ft room, we recommend looking for an air purifier with a CADR rating of at least 300.

2. The specific features

The next thing to look for is the specific features that you need. Some air purifiers come with built-in ionizers, while others have UV light technology. If you have specific allergies, you may want to look for an air purifier with a HEPA filter.

3. The reviews

Finally, take into account the reviews of other customers. Look for an air purifier that has a high customer satisfaction rating and has been recommended by other customers.

Important features of the air purifier for 400 sq ft

Air purifiers for 400 sq ft are designed to remove airborne contaminants such as dust, pollen, mold spores, and pet dander from the air in your home. Some models also feature activated carbon filters that can remove smoke, odors, and VOCs (volatile organic compounds). Here are some important features to look for when shopping for an air purifier for 400 sq ft:

  • HEPA filter: A high-efficiency particulate air (HEPA) filter is the gold standard for removing airborne contaminants. HEPA filters can remove 99.97% of particles that are 0.3 microns in size or larger, making them ideal for homes with allergies or asthma.
  • Activated carbon filter: Activated carbon filters are great for removing smoke, odors, and VOCs from the air. Some air purifiers for 400 sq ft feature both HEPA and activated carbon filters for maximum air quality.
  • Ionizer: An ionizer emits negative ions that attach to positively charged particles in the air, such as dust and pollen. These heavier particles then fall to the ground, where they can be vacuumed up or wiped away.
  • UV light: Ultraviolet (UV) light is effective at killing bacteria, viruses, and mold spores. Some air purifiers for 400 sq ft feature a UV light to help improve indoor air quality.
  • Ozone generator: An ozone generator emits ozone, a gas that can remove odors and VOCs from the air. However, ozone is also a lung irritant, so it's important to choose an air purifier with an automatic shut-off feature if it will be used in a home with children or pets.
