When it comes to air purification, the debate between two smaller air purifiers and one big one is a common one. The answer to this question depends on the size of your home and the type of pollutants you are trying to remove. Placing two air purifiers in different locations in the room can help improve air circulation. This is because they can attack pollutants in different rooms more effectively.
For example, an air purifier used in a kitchen or bathroom may need to better target odors from harsh cleaning products, while one used in a garage may require a greater focus on VOCs. If your home is larger than 500 square feet, you'll need more than one air purifier to ensure clean air in each room. Not everyone has the same health status and tolerance level for air quality. A family member could have problems with domestic pet dander, while another person may suffer from MCS but not have any issues with pets.
Therefore, it makes sense to have an air purifier in every room. This will ensure that indoor air is always clean and free of dust, dust mites, pollen, mold, pet dander, chemical smoke, bacteria and viruses. Having more than one air purifier at home will also help reduce the risk of allergies and other illnesses. You'll need enough units to manage the volume of airspace (in other words, room-size coverage) where you have air quality issues.
For a large 3,200 square foot house, two air purifiers are enough to provide an air change per hour. If you're on a tight budget and can't afford multiple air purifiers, choose a single medical-grade HEPA air purifier with the portability for room-to-room purification. Make sure the air purifier is working and leave it on all day, all night, to enjoy a constant flow of clean air. We recommend supplementing the whole-house HVAC air cleaning system with one or more air purifiers throughout the house for better efficiency.
No matter what size your home is or what type of pollutants you are trying to remove, it's important to make sure your air purifiers have easy access and enough space to work properly. Most air purifiers have a low energy consumption rate identical to that of other smaller appliances.
