If the purifier is turned on for a considerable amount of time with little or no change in air quality, you will know that the purifier does not work. This will depend on a number of factors and what you are looking for the air purifier to do. The size of your home, the level of impurities in the air, and the power of the purifier will affect how long it takes that air purifier to do its job, as well as the number of times the air changes per hour. If you're looking for a reduction in bad odors, you can expect an air purifier to do its job in a day or so.
That said, you'll also want to know how long it takes an air purifier to clean a room, how long HEPA filters last, and the best way to maximize the efficiency of an air purifier. All air purifiers use a powerful fan to suck polluted air out of the room and expel clean, pollutant-free air from the other end. You can check if your fan works by listening to the operating noise or using the palm of your hand to feel the breeze. The first step is to test the airflow.
In general, an operating air purifier will constantly blow clean air into the room. If this isn't happening and you can't feel the air flow, there must be some problem with the air purifier. You can easily check the air flow by placing your hand in front of the air purifier unit. We mentioned that the right type and size of air purifier could significantly lower the air cleaner.
Every little effort counts. A selling point for whole-house air purifiers is that you install them in one place, but they clean the air throughout the house. To maintain the air quality level in the room, switch to low speed and allow the air cleaner to run continuously in the background, as pollutants in the air will circulate non-stop throughout the day. Needless to say, the closer the air purifier is to the source of the odor, the faster the air will be cleaned.
Alternatively, you can place the air purifier at a strategic point in the room where you can clean all the air in the room with ease. Oddly enough, using your air purifier in the summer is different from using your air purifier during the winter. We hope this post addresses the misconception that running an air purifier for a few hours is enough to provide you with clean air for the rest of the day. Over time, a thick layer of dust particles, mold, pet fur, and other contaminants builds up in air filters.
For example, furniture that blocks airflow, close cooking, and normal air cleaner filter wear will reduce ACH. If you find an improvement in your air quality reading, then you will definitely know that your air purifier works efficiently. The CADR (Clean Air Supply Rate) rating indicates the volume of air the purifier can move to clean 80% of contaminants. The only time you shouldn't use an air purifier is when there is a safety hazard, such as a damaged power cord, an ozone generator that diffuses harmful ozone, or dirty filters that hinder your filtration efficiency.
Your air purifier will find it difficult to push air through a full filter, limiting its working efficiency.
