Objective third-party data shows that air purifier effectiveness is not correlated to price. Or put another way, there are plenty of poor-performing expensive machines out there (such as the Swiss Air in this test) and plenty of high-performing cheap machines out there.
Yes, more expensive air filters can make a difference, but the extent of that difference depends on several factors: Filtration Efficiency: Higher-priced filters often have better filtration ratings (like MERV ratings), which indicate their ability to capture smaller particles.
Top rated units fall in the $120 to $200 range. We generally do not recommend units that cost less than $100 (If you find this price range unaffordable we recommend that you hold off on your purchase - it's that important). More expensive units are also not recommended.
EPA recommends looking for air purifier models that provide at least 4.8 ACH for the recommended room size to help improve your indoor air quality. A device labeled to provide 4.8 ACH in a 10'x12'x8' room can treat the air in a room of that size 4.8 times each hour.
The reality is, air purifiers offer an effective option for helping remove particles from the air that circulates in your home. How effective depends on a number of factors, starting with the quality of the air purifier. A high-quality whole-home air purifier filters the air for your entire home.
Ozone-Generating Air Cleaners
One mechanism of damage results from ozone-olefin reactions, and another from ozone reacting with electron donors (such as glutathione). Inhalation of relatively small amounts of ozone can cause coughing, chest pain, throat irritation, and shortness of breath.
What are the downsides of air purifiers? There aren't a lot of downsides to having an air purifier in your home aside from the financial investment. Many ionizers, especially older models, can generate ozone when they are operating, which is known to exacerbate asthma.
Many people think that switching it off during the night or when they're not present is a logical energy-saving measure, but it is recommended to keep it running constantly. Once you turn off your air purifier, the air quickly becomes contaminated again with mold, dust, dander, and other pollutants present in the air.
Room air cleaners are portable, electric appliances that remove fine particles, such as dust and pollen, from indoor air. A standard room air cleaner, operating continuously, uses approximately 450 kWh per year in electricity. This is more than the energy used by some new refrigerators!
For context, electricity usage is a minor factor in the cost of air purifier ownership. The cost to run Alen's largest unit, the 75i, on its top fan speed 24/7 for a year is likely less than $50. Customers typically run the unit on speed 2 or 3, so the average cost is likely less than $25 for an entire year.
A whole-house air purifier is undoubtedly worth the money for those with allergies, asthma, and other respiratory conditions. The system helps reduce symptoms by removing antagonistic air pollutants. This results in less frequent and intense allergy and/or asthma attacks.
The energy cost of running an air purifier continuously is surprisingly low. Even a powerful whole house air purifier that covers up to 4,000 sq. ft. can cost just $0.27 a day, and that's when run continuously on the highest setting.
Expensive air filters are made from higher-quality materials, like fiberglass, that can last for up to 12 months. This not only saves you money, but it's also more convenient since you won't have to remember to replace your air filters as often.
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.
Keep your device away from moisture or areas with high humidity. Place your device at least 6 inches from walls, furniture, or other items while in use. Place your air purifier near the most likely source of indoor air pollution. Consider investing in an air purifier that shuts off automatically with a timer.
Air purifiers assist in eliminating household dust by helping to clean and purify the air in the home. Dyson's advanced purification machines are engineered with technology that traps dust before it settles on your furniture and floors. Dyson purifiers capture 99.95% of dust and ultrafine particles1.
In a typical home environment, an effective air purifier can start to reduce these pollutants within 30 to 60 minutes. Noticeable improvements in air quality are often observed within a few hours, with significant reductions occurring over 24 hours of continuous use.

Airocide is the NASA air purifier. Our technology removed harmful VOCs from the International Space Station and the Columbia shuttle.
Air circulation: If your room has poor air circulation, or is a complex shape (such as an L shape or a long thin shape) then you may benefit from multiple smaller air purifiers to improve ventilation. Two air purifiers placed at different locations in your room may help improve air circulation.
Placing an air purifier in your bedroom can allow you to breathe clean air for hours at a time, which you may not be able to experience during the day. However, to get the most benefit to your indoor air quality, you should make sure that your air purifier is in an ideal spot, like your nightstand, while you sleep.
Medical professionals suggest prioritizing maintaining a clean home and frequently sanitizing frequently used surfaces. Air purifiers should just be an accessory to your cleaning routine, not a priority.
The first is related to their cost. A high-quality HEPA filter can cost anywhere from a few hundred dollars up to several thousand depending on the size and model and the area to be covered. Secondly, they need to be regularly maintained and replaced in order to keep them working properly.
