What is the #1 air purifier? ›

Whether you're experiencing seasonal allergies, wildfires or illness, an air purifier can help keep your air clean. After testing air purifiers at a variety of price points from different brands, we found that the best air purifier you can buy is the BlueAir Blue Pure 311i Max.

Headaches, sore throat, coughing, Asthma attacks, and difficulty breathing are a few of the symptoms that can be brought on by some air purifiers. Yes, that's right. Your air purifier may actually aggravate many of the health issues you hoped it would solve.

While air purifiers may not directly or immediately improve a person's health, studies indicate that these devices can help to reduce your exposure to harmful pollutants, which may have long-term health benefits.

A house with 2 or 3 floors, air purifiers cannot pass through walls, corners, hallways, or even downstairs to purify the air in a living or workspace. This means that home with multiple rooms often require multiple air purifiers. It also means that indoor spaces with open floor plans may require fewer purifiers.

Placing the air purifier on the ground is usually ideal. One reason is that gravity causes more dust and heavier particles to settle to the ground, so dust concentrations tend to be higher in the air near the ground. Air purifiers placed on the ground can capture these dust particles more effectively.

Part of the reason that HEPA filters are so rarely used in HVAC systems is that they are extremely restrictive in terms of airflow. This means that the system needs to be extremely powerful and use additional fans in order to properly draw air through the HEPA filter and circulate it throughout the room or building.

Air purifiers don't cause sinus problems. In fact, they can actually help if the problems are caused by airborne irritants. Air purifiers filter out the dust, pollen and dander that may be triggering your allergies and inflaming your sinuses.

If you have more air purifiers than is necessary, you do stand the chance of over-purifying the air in your home and using more energy than necessary.

Cleaning the air of these pollutants can allow better breathing leading to better sleep. A recent study found sleep quality improves significantly when air pollutant levels are lowered.

Air purifiers can be effective in removing dust indoors and improving asthma and allergy symptoms. They come with different filters, but studies show that HEPA filters can remove most airborne particles, including pollen, mold, and bacteria. A person should also choose a device compatible with their room size.

Do air purifiers help with mold? ›

Using an air purifier can help improve indoor air quality by trapping mold spores. However, you will still be subjected to the other indoor air pollutants that were not trapped. Due to this fact, an air purifier may remove mold from the immediate environment but it will not get rid of all of the spores in your home.

The most important room to put an air purifier in is the bedroom — yours as well as the bedrooms of your children. This is the room where you spend the most time because this is where you sleep.

Won't remove every particle: Unfortunately, HEPA filters will not remove pollutants from the air that are smaller than 0.3 microns, including viruses, some bacteria, and volatile organic compounds (VOCs).

An air purifier is your best bet to improve indoor air quality and reduce allergens. A dehumidifier is a clear choice if you're concerned about high humidity levels and potential mold growth. However, if you live in a humid climate or the air in your home feels stifling, a dehumidifier can regulate the humidity level.

In many cases, one air purifier is sufficient for a single room, as long as it's rated to cover the square footage of that room. However, extremely large rooms, or rooms with ceilings higher than 8 ft.¹, might require more than one air purifier due to their larger square (or cubic) footage.

As a rule of thumb, the CADR of your air cleaner should be equal to at least two-thirds of the room's area. For example, a room with the dimensions of 10 feet by 12 feet has an area of 120 square feet. It would be best to have an air cleaner with a smoke CADR of at least 80.

The higher the CADR, the better. At minimum it should be 100. CADR determines the rate at which air is cleaned inside the room. With a high CADR purifier, more air in your room will be cleaner at a point of time.

Unlike HEPA Air Purifiers, Electrostatic Air Purifiers do not use filters. Instead, owners are instructed to rinse out the internal filtration system every four to six weeks. HEPA Air Purifiers, like all Alen Air Purifiers, use HEPA style filtration to capture and remove particles from your indoor air.
