Ensure your air purifier has enough clearance around it to function optimally. Avoid placing it behind furniture or in tight corners where airflow might be restricted. Ideally, there should be at least 3-5 feet of clear space around the unit to allow for unimpeded air intake and output.
Keep Your Air Purifier Away from Heat
Air purifiers work hard and can get hot after a period of use. To prevent overheating and potentially damaging your device, keep it away from vents or radiators. Avoid running your unit for sustained periods while it is in direct sunlight.
The short answer: yes. The Asthma and Allergy Foundation of America (AAFA) recommends an air purifier during bedtime to promote better breathing while you sleep.
For this reason, the equipment can stand in the living room during the day, while in the bedroom at night. Do not forget about the height of the position of the purifier. Specialists recommend placing the device on the floor, because it is near the ground that there is a higher concentration of pollutants.
Air purifier floor placement is great for heavier particles like dust and pet hair, while elevated placement offers better coverage for lighter pollutants at breathing levels.
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.
When it comes to choosing a surface to place your air purifier, stability and functionality are key considerations. It's best to put your device on a hard, flat surface. For example, a hardwood floor, tile floor, or short carpeting.
The living room is a great room to put a purifier in because it is shared by the entire family. This means that everyone's sensitivities collide there. To keep everyone comfortable, keep the air in this space clean.
Clinical Study: A study published in the Environment International evaluated the impact of HEPA air purifiers on indoor particulate matter levels. The researchers found that using portable air cleaners with HEPA filters resulted in substantial reductions in indoor dust concentrations, leading to improved air quality.
This is why most manufacturers will recommend you to leave your air purifier running all day, especially if it comes equipped with an automatic setting. This setting allows your device to monitor the quality of your air in your home for you and to adjust its speed depending on the levels of pollutants that it detects.
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.
Air purifiers work the best when they are used in confined spaces such as closed rooms. You can open the doors and windows for proper ventilation and a supply of fresh air during the day. However, make sure that you close the doors and windows when you use the air purifier.
We recommend elevating it no higher than 5 feet off the ground, and this can be done by placing the air purifier on a piece of furniture, such as a dresser.
In theory, you would get the best results by having an air purifier in every room of your home. However, the cost of doing this can make it impossible for most people. If you're wondering whether you need an air purifier for each room, start with an affordable two: one for your bedroom and one for the living area.
Mold is an obvious health risk in any home, but investing in an air purifier can help limit your exposure. The best among them will ideally offer HEPA-level filtration, with this level of filtration being able to trap up to 99.97% of airborne particles down to 0.3 microns in diameter.
Certain regulatory bodies have taken action on this issue and air purifiers that generate ozone are actually banned in some places. Certainly, these products generate significant amounts of ozone that, if inhaled, can cause long-term damage to olfactory cells and lungs.
Why is my room dusty with an air purifier? Dust may still accumulate due to poor filter maintenance, inadequate air circulation, or insufficient filtration power. Regularly replace filters and ensure good airflow.
As you can see, air purifiers are designed to clean the air, while humidifiers and dehumidifiers are used to regulate moisture levels. An air purifier won't have any effect on the humidity in your home, but it will improve air quality.
Place your air purifier in a central area of the room to allow for efficient airflow and circulation. This means you should keep your device away from walls, corners, and other obstructions (more on why in a second).
When an efficient, effective, safe unit is selected, whole house air purifiers: Offer air purification without “boundaries” – they clean the air in your entire home. Eliminate the need for multiple air purifiers around the house. Provide air purification without taking up space in the living area of the house.
If you can open a window in a room while the air purifier is working, it is not a bad idea to mix in a little fresh air, as well. Doors opened or closed, it does not really matter. The air purifier is going to clean the area it is immediately contained to, regardless.
Air Purifiers Should Be Placed on the Floor in Most Cases
So placing the air purifier lower helps capture these pollutants effectively.
Pre-filters should be gently vacuumed every 1–3 months. Many air purifiers have a pre-filter that captures larger particles like hair and dander before they reach the main filter, protecting your main or carbon filter so it doesn't clog up as quickly. Clean pre-filters frequently, about every 1–3 months.
You may want to hide your purifier behind or below some furniture to keep it out of sight as they are not always the nicest looking things—don't do this. Air purifiers should have at least three feet of space between it and something else, which will allow for optimal air flow.
