Most air purifiers are portable for a reason – so you can move them around, as needed, to maximize their efficiency. Doing so also increases access to polluted air that might need cleaning.
You can definitely move your air purifier between rooms, but it's not the most effective strategy. Air purifiers work best when they run continuously in a single space, as it takes time to clean the air and maintain low levels of dust and allergens.
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.
Can One Air Purifier Work for Multiple Rooms? In general, yes—one air purifier can work for multiple rooms. However, it's important that the unit's capacity fits the layout of your home and is specific to the type of air pollutants you're targeting.
Regardless of where you live, the good news is, air purifiers do not use a lot of electricity to operate.
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.
When running 24/7, most HEPA air purifiers rated 50 to 100 watts per hour would only set you back around $4 to $10 monthly or $72 to $120 in a year.
If you have more air purifiers than is necessary, you do stand the chance of over-purifying the air in your home and using more energy than necessary.
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.
By positioning the air purifier near your bed, you can create a localized zone of cleaner air, which can be especially comforting for those with respiratory conditions. Ensure that the air purifier is placed at a safe distance from your head to avoid direct air exposure during sleep.
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.
It's perfectly safe to keep the device running continuously, and the amount of energy it consumes is very small.
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.
Since air will flow wherever there is an opening, the air purifier will try to pull in air from outside if doors are not fully closed. This may seem counterintuitive, because often open doors and windows to let fresh air in.
Air purifiers remove dust, smoke, bad smells, harmful chemicals, viruses, pollen, and pet dander. They provide fresh and clean air, which is essential considering the rise of pollution in the world. They're not just used at home.
Typically, a high-quality air purifier like those from Alen can start showing noticeable air quality improvements within 30 to 60 minutes. However, achieving optimal results throughout your entire space can take several hours, depending on the conditions.
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. Place your air purifier in a room where you spend most of your time.
Air circulation: If your room has poor air circulation, or is a complex shape (such as an L shape or a long thin shape) then you may benefit from multiple smaller air purifiers to improve ventilation. Two air purifiers placed at different locations in your room may help improve air circulation.
Whole-house air purifiers work to remove harmful particulates from your home's air such as mold, pet dander, airborne viruses, pollen, and odors. Our whole-house air purifiers help create Healthy Air for your entire home, not just space or a room, and can help reduce triggers for allergy and asthma sufferers.
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.
Most air purifiers consume between 30 and 250 watts of electricity, with the average unit using around 50 watts. To put this into perspective, a typical 60-watt incandescent light bulb uses more energy than many air purifiers.
People who buy ozone generators may not be aware that ozone can harm the cells in the lungs and respiratory airways. Exposure to ozone irritates and inflames the lining of the respiratory system. This causes symptoms including coughing, chest tightness, shortness of breath, and impaired breathing.
Is It Safe to Leave an Air Purifier On While You're Away? Leaving an air purifier on while you're away from home is generally considered safe, as most modern air purifiers are designed for continuous operation.
The lifespan of an air purifier can vary depending on several factors, including the quality of the device, frequency of use, maintenance, and the type of filtration system it employs. On average, air purifiers can last between 5 to 10 years.
When used correctly, air purifiers with HEPA filters can effectively reduce dust and other allergens in the air. They may be particularly useful if you're allergic to dust mites or pollen or if allergens trigger your asthma.
