Honeywell sells air purifiers made with true HEPA filters or Permanent Washable Features, and uses third parties to independently verify any energy or air filtration claims. The company sells a wide range of purifiers that are suitable for most rooms and budgets.

People may use air purifiers due to concerns about asthma, allergies, air pollution from smoke, or other particles that may negatively impact respiratory health.

This article discusses what Honeywell is, its air purifiers, and any health benefits of using these devices.

The company states that it has fast delivery, with most items packed and shipped the same or next business day. Honeywell also offers a 30-day return policy on all of its products and aims to answer any queries with its United States-based support staff.

Honeywell has several Better Business Bureau (BBB) pages. At the time of publishing, none of the pages hold accreditation with the BBB.

Honeywell has an average customer review rating of 3.9 stars out of 5 on Trustpilot. The customer who left a positive review states that the support staff was quick to update their order when they realized they had bought the wrong part.

Negative reviews state that Honeywell did not adequately solve after-sales issues. One customer said that the company did not honor its return and warranty policy. Other reviewers say that they experienced delays with the shipping of replacement parts.

Air purifiers are devices that people may use to clean the air. Air purifiers come in different sizes and many are portable. Usually, a larger room requires a larger air purifier.

These devices remove particles from their air. Some common types of air purifiers include:

  • Ultraviolet air purifiers. These devices remove particles from the air using ultraviolet (UV) light.
  • HEPA air purifiers. These devices can remove small particles, such as pollen, dander, and dust from the air, which may be more suitable for people with allergies.
  • Activated carbon air purifiers. People may use these devices to remove odor and smoke from the air.
  • Ionic air purifiers. These devices release ions into the air which become charged when they come into contact with particles such as dust. The charged ions and particles then fall from the air.

An important factor to consider when purchasing an air purifier is the device’s clean air delivery rate (CADR). A larger room will require a higher CADR.

The Environmental Protection Agency (EPA) recommends the following CADR for different room sizes:

Minimum CADR65130195260325390
Room size (square feet)100200300400500600

Air purifiers can improve the air quality inside a room or building.

A 2018 study on older adults found that portable air filtration devices limited the participants’ exposure to fine particles and reduced their blood pressure. The researchers note that although short-term use of these devices can limit exposure of particles and reduce blood pressure in suburban settings, further research is needed.

A 2017 pilot study notes that air purifiers in living rooms and bedrooms may improve the symptoms of asthma and allergic rhinitis in children. The air purifiers in this study reduced the number of particles in the air by 43%.

However, recent research suggests that, while air purifiers can reduce the number of particles in the air, there is not enough evidence to suggest that the devices improve health.

The EPA recommends looking for the following when shopping for an air purifier:

  • CADR. People should ensure the CADR is large enough for the size of the room.
  • Type of purifier. The EPA recommends using different types of purifiers for different needs, such as using an activated carbon filter to remove gases and odors.
  • Avoid ozone air purifiers. The EPA states that people should avoid air purifiers that intentionally emit ozone, as this is a lung irritant.
  • Decibel rating. The EPA recommends selecting a model with a lower decibel (dB) rating to reduce noise.

Honeywell sells a wide range of air purifiers. The following are a sample of the air purifiers the company offers.

The company states that all orders are shipped during weekdays. Orders over $250 will incur insurance fees.

Honeywell offers a 30-day return policy. People will have to pay for shipping and pay a restocking fee of 10–30% unless the product is damaged.

Below are some frequently asked questions about air purifiers.

Do air purifiers work?

Air purifiers can remove particles from the air but they cannot remove all potential contaminants.

While there is some evidence that air purifiers can benefit health, recent research has shown that the health benefits are not clinically significant.

Do air purifiers help with COVID-19?

There is some evidence that air purifiers can reduce the amount of COVID-19 particles in the air. A 2020 study found that aerosol particles of the SARS-CoV-2 virus are within the size range that HEPA filters can remove.

The researchers state that HEPA air purifiers can remove particles the same size as COVID-19 particles with 95% efficacy.

However, this study is weak and limited, and more research is needed. People should not rely on air purifiers to avoid contracting COVID-19.

Air purifiers can help remove particles and other contaminants from the air. Honeywell manufactures a variety of different air purifiers, made with HEPA or Permanent Washable Filters, that are suitable for a wide range of room sizes.

While there is some evidence that air purifiers have health benefits, such as reducing symptoms of asthma and allergic rhinitis and lowering blood pressure, more research needs to be conducted.
