The ideal placement depends on the type of air purifier you have and your primary pollution concern:
While norovirus is not airborne in the same manner as the flu is, it can still spread through the air in contaminated droplets. Using an air purifier can help capture these particles before they reach other individuals in the home, offering another line of defense against norovirus.
Elevated Placement for Better Breathing Zone Coverage
Positioning it 2 to 5 feet off the ground places it directly in the breathing zone. Most people breathe air from this height range whether sitting, working, or sleeping. An elevated purifier can intercept airborne particles before inhalation.
An Eoleaf air purifier is an indispensable device for those undergoing chemotherapy or recovering from other cancer treatments. With their HEPA H13-certified filter layer, our devices remove 99.97% of all pollutants down to a size of 0.01 microns in a single pass.
Again, installing an air-purifying machine and/or humidifying system to a home or business can help not only relieve post-nasal drip, but it can also help prevent it. Keeping homes free and clean from dust particles and dust mites helps as well.
You lie awake wondering if the gentle hum from your air purifier will keep you up all night. Or maybe you're concerned about running electronics while you sleep. These worries are common. The truth is that sleeping with an air purifier on is not just safe—it's one of the best things you can do for your health.
Follow the 2/3 Rule
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.
For people with allergies, scientific studies have shown that air filtration reduces these airborne allergens and may provide some relief. Experts recommend two types of filtration: For a single room, look for an air cleaner with a HEPA (high-efficiency particulate air) filter.
No. Air purifiers do not dry out the air. Air purifiers are designed to filter airborne pollutants—like dust, pollen, pet dander, smoke, and some microbes—without removing moisture from the air. Dehumidifiers are appliances built to lower humidity; air purifiers are not.
The evidence is apparent, in chronic respiratory diseases, such as asthma and in cardiovascular health. Technologically advanced air filter systems are now available which efficiently remove particulate matter, resulting in significant health benefits to patients of asthma and cardiovascular disease.
Elevate the Device
In rooms where you're sitting, like a living room or office, the device can be closer to the ground, but in rooms where you predominantly stand, a slightly higher elevation tends to be more effective. Note this technique is only effective for small, portable air purifiers.
Lighter airborne contaminants like smoke, cooking odors, and certain chemical vapors (VOCs) tend to rise and circulate at higher levels in your room. For these pollutants, elevating your air purifier on a table or stand between two and five feet off the ground can improve capture efficiency.
Keep the air purifier at least a foot or two away from televisions, computers, and fans. Electronics can interfere with air quality sensors on smart models, and fans or heating vents create competing airflow that reduces the purifier's ability to circulate air through its filters effectively.
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.
Can air purifiers remove all viruses and bacteria? No. HyperHEPA filtration can remove at least 99.5% of airborne viruses and bacteria down to 0.003 microns. However, no filter can guarantee 100% removal, and pathogens on surfaces or transmitted through direct contact are not addressed by air purification alone.
Reverse osmosis (RO) water filter can be used to eliminate germs and viruses. UV kills bacteria & viruses and RO membrane removes these bacteria and viruses.
Myth 4: Air purifier reduces immunity to outdoor pollution
In fact, having an air purifier will limit its intake by letting you breathe clean and healthy air inside. This will, if anything, protect your health by reducing the daily average exposure level to the polluted air.
Common symptoms
You don't need an air purifier in every room, but you do need coverage in the rooms where you spend the most time and where air quality most significantly impacts your health and comfort.
Air purifiers do not dry out the air. In fact, they don't affect indoor humidity levels at all. They simply circulate the air and remove contaminants.
The ideal indoor humidity level for sleeping is between 30% and 50%. Maintaining this range helps prevent dry skin, irritated sinuses, and congestion, all of which can disrupt restful sleep. Too little humidity can dry out airways, while too much can promote mold growth and dust mites.
Can an air purifier reduce humidity? No. Air purifiers filter particles from the air but do not remove moisture. A dehumidifier is required to lower indoor humidity levels.
This depends on the filter type and usage: HEPA filters: Every 6–12 months. Carbon filters: Every 3–6 months. Washable filters: Rinse every 2–4 weeks, replace every 6–12 months if reusable.
In addition to opening windows and using the kitchen vent, you can remove cooking odors and kitchen smoke with a kitchen air purifier fitted with a SmokeStop™ filter. The filters use activated carbon formulated with magnesium dioxide and copper oxide, making your kitchen air smell fresh and clean.
