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.
However, in general, the duration of use required depends on the size of your space and the amount of indoor pollution (which varies throughout the year). 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.
Leaving your air purifier turned on throughout the whole day is the best move. United States Environmental Protection Agency depicted that running air purifiers all day long removes certain respirable-size particles like tobacco smoke particles.
Regardless of where you live, the good news is, air purifiers do not use a lot of electricity to operate.

Studies found that when using auto or smart mode on air purifiers, indoor air was double the WHO average PM2. 5 limit for 24 hours. That's why you can never depend on your air purifier's auto or smart modes to keep your air clean.

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 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.
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.
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.
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.
An air purifier and specific filters effectively eliminate harmful gases and unwanted odors from your indoor environment. A standard particle filter is not designed to remove gases and odors. For gas and odor removal, the air purifier should be equipped with a filter that includes activated carbon.
Air purifiers help reduce allergens and pollutants, but improper use can have health risks. Overuse of ozone-producing purifiers can irritate the respiratory system. Additionally, if filters are not replaced regularly, purifiers may become less effective, leading to poor air quality.
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.
Regularly replacing filters and ensuring adequate airflow throughout the room will help reduce dust levels. Additionally, choosing an air purifier with higher CADR ratings for your space size may be necessary to effectively remove particles from 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!
A whole-house air purifier is an air filtration system that is installed in the HVAC system of a house to clean the air in the entire home. These systems clean indoor air by using a filtration system that circulates the air from your HVAC system and removes pollutants such as allergens, dust and pet dander.
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.
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.
Turn purifiers off when you aren't home or spending time in the space. If you use an air purifier in your bedroom while you sleep, instead consider turning it on for just a couple of hours before bedtime, and turning it off while you sleep. Additionally, be sure to turn your air purifier off while you're at work.
Every day leave it on for at least 4 hours. If there is a noticeable smell in the room, it is recommended to keep an air purifier on for 8 hours or even longer. In this way, it can have a good indoor purification effect and discharge harmful indoor gases to the outside as soon as possible.
According to Li, air purifiers are most important for people who are sensitive to particles because they have asthma, allergies to pollen or dust, or cardiovascular issues, as well as children, pregnant people and the elderly.
