If you suffer from lung disease, you might be considering getting air filters from www.amazon.com/BNX-20x20x1-MERV-Filter-Pack/dp/B09XC3RQ3J. Air filters might not be necessary if your environment is clean. It is important to take the time and learn about each type of filter.
Pleated air filters
A pleated filter is a long-lasting, high-quality replacement for standard HVAC systems. The filter traps more dust and allergens because it has a larger surface area than a standard flat filter. A pleated filter can last for 60 to 90 day before it has to be changed. Pleated air filters can be quite expensive. Choosing between a non-pleated and pleated filter depends on your needs and your sensitivity to pollutants.
Flat-panel air filters
Two types of home air filters are available: flat-panel or pleated-panel. These basic filters are made of non-electrostatic material and capture large airborne particles like household dust and lint. Flat-panel air filters cost less and are best for medium-sized rooms. They are also less polluting than other types. Flat-panel air filters do not have an electrostatic charge and are best suited for small rooms with minimal furniture.
Oil bath air purifiers
Oil bath air cleaners do not require a lot of maintenance, but they do need to be serviced regularly. In dusty conditions, oil level may increase, so regular servicing is necessary. To service an oil bath air cleaner, take it apart and pour kerosene in the cleaning cup. Oil bath air cleaners can move air between 1.4 and 19 cubic meters per hour.
HEPA PRACs are air filters that use HEPA technology to reduce PM levels. Despite their claimed effectiveness, they have a limited track-record. However, there have been conflicting results from studies on humans and animals. According to one study, HEPA PRACs have no measurable effect on the concentration of a cat’s allergen. However, further studies are needed to determine the exact effectiveness of these filters. There are several important considerations to make when choosing air filters for indoor use.
