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.
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.
Are there any times you shouldn't run your air purifier? It's advised to keep your air purifier turned on all day and night, even when you're sleeping or not at home.
Do not use an air purifier that employs ionization technology. It produces harmful ozone (a lung irritant) and the technology encourages harmful particles to stick within your lung tissue. The ionizer charges particles that would otherwise be neutral and thus encourages them to stick to a negative field.
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.
Signs That Your Air Purifier Produces Ozone
Product Information: Manufacturers are required to disclose if their products produce ozone. Check the product specifications, user manual, or the manufacturer's website. Look for any mention of ozone generation or emission levels.
Regardless of where you live, the good news is, air purifiers do not use a lot of electricity to operate.
At the 15-minute mark, the air is 50% as dirty as it was before turning on the purifier. After 80 minutes, the air is just as dirty as it was before. This means that if you turn off your purifier before sleeping, for most of the night your air will be just as bad as not having a purifier.
Health Benefits: Using an air purifier in the bedroom can provide numerous health benefits, including reduced risk of respiratory infections, improved cardiovascular health, and enhanced overall well-being.
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 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.
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.
Studies suggest that air purifiers that contain HEPA filters. View Source are effective at reducing some symptoms of allergies and asthma. High-Efficiency Particulate Air (HEPA) filters trap allergens and particulates in the air, making it less likely that they'll be inhaled during sleep.
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.
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.
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.
When used properly, air purifiers can help reduce airborne contaminants including viruses in a home or confined space. However, by itself, a portable air cleaner is not enough to protect people from COVID-19.
Research suggests that clean air possibly helps boost life expectancy. Air purifiers prevent harmful chemicals and pollutants from building up and impacting wellness or worsening health conditions. Indoor air is two to five times more polluted than outdoor air. Prioritizing healthy indoor air is essential.
Heating and cooling: 45-50%
The largest electricity consumer in the average household is your heating and cooling appliance. By a long shot. Central air conditioners and heaters use tons of energy in order to keep your home set to the right temperature.
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.
Headaches, sore throat, coughing, Asthma attacks, and difficulty breathing are a few of the symptoms that can be brought on by some air purifiers. Yes, that's right. Your air purifier may actually aggravate many of the health issues you hoped it would solve.
Do not use an ionizer in an enclosed space when someone is present. Either open a window or run the ionizer when no one is home, turning it off whenever anyone is in the room with it.
