Yes, by using HEPA filters in both vacuum cleaners and air purifiers, the user can reduce the amount of allergens and airborne pollutants in a home. HEPA filters are designed to capture particles of 0.3 microns or more, such as pet dander and dust, which can penetrate the lungs and cause problematic reactions. In addition to HEPA filters, some air purifiers also have an ionizing function to help reduce odors and fumes. It's important to distinguish between HEPA air purifiers and True HEPA air purifiers to ensure your needs are met.
When it comes to air purifiers, it's important to look for one with a high Clean Air Delivery Rate (CADR). CADR is a measure of how quickly an air purifier can filter out particles from the air. The higher the CADR, the more effective the air purifier is at removing particles from the air. Additionally, it's important to inspect and clean or replace the filters regularly once a month to maintain optimal performance.
The Molekule Air is one example of an air purifier that uses a HEPA filter. In Auto (similar to medium; the air does not contain a particle counter to adjust to air conditions, but instead asks you to enter the approximate size of your room, after which the machine chooses a fan speed that Molekule deems appropriate), the air performed worse, reducing particles by 0.3 microns at only 18.0% (ambient) and 26.4% (clean). In Silent, it performed even worse, reducing 0.3 micron particles by 6.5% (ambient) and 7.2% (clean). And in Dark plus Auto, with its primary PECO purification system turned off and its fan at the equivalent of a medium setting, it reduced them by 21.3% (ambient) and 18.0% (clean).
Interestingly, those numbers closely reflect our results in automatic configuration with the PECO system activated, suggesting the possibility that the Molekule Air relies primarily on its physical prefilter, not its patented PECO mechanism, to remove particles. The Dyson Pure Cool TP04 is another example of an air purifier that uses a HEPA filter but does not provide CADR. The Coway Mighty is another popular option that has an ionizing function in addition to its HEPA filtration. It also has an attractive cylindrical shape and tweed-like cloth cover which acts as a pre-filter; you can wash it to maintain optimal pre-filter performance. It's also important to remember to replace your purifier filters regularly and set a calendar reminder for this task. Not all air purifiers clean the air equally; some are more efficient than others and some are designed for large or small rooms.
Additionally, some can be hazardous to health if not used properly. Finally, it's important to note that HEPA filters do not capture volatile organic compounds (VOCs) or odors and fumes effectively. To address this issue, some air purifiers have activated carbon filters which can help reduce odors and fumes for a short period of time.
