But an air purifier can actively remove key sources of pollution, helping you rest easy, literally. For maximum benefits, position the air purifier about 6-10 feet from the head of your bed.
Using an air purifier while sleeping is generally the same as using one while awake. If you are sensitive to dryness, then it might be best to be sure that the purifier isn't blowing directly into your face. Otherwise the air that an air purifier moves while you sleep is the same as a fan – just cleaner.
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.
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 work by forcing air through the filters to remove pollutants. Every time you turn off the purifier, pollutants begin to accumulate again, making it more difficult for the purifier to do its job. Leaving the air purifier on continuously will allow new contaminants to be removed as they are introduced.
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.
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.
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.
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. Setting it on a shelf can significantly reduce the filtration efficiency.
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.
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!
First, check the system's airflow. A working air purifier features clear, consistent airflow. If the purifier is not blowing out air (easily determined by placing your hand in front of the system), there's likely a problem. If you are unable to hear anything, that's also a sign the purifier isn't working.
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.
In principle, installing a ventilation system and/or an air purifier will relieve you of the need to air your home, but an additional supply of fresh air may still be useful in some cases: When you have just used paint, glue or other chemicals in your home.
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.
Some ideal places to keep the air purifier within the bedroom are near your bed, on a nightstand, or mounted onto a high shelf; this will maximize the elevation and ensure an equal amount of fresh air distribution throughout the room.
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.
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.
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.
Recent research by researchers from the University of Reading and the University of Sussex, commissioned by Dyson, has found that using an air purifier can have a positive impact on sleep outcomes.
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.
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.
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 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.
