When it comes to air filters, the old adage 'you get what you pay for' is often true. Generally, more expensive air filters are more effective, but the amount of filtration you need depends on your individual circumstances. For instance, a single person without pets and allergies may not require as much filtration as a family of five with three pets and a child with asthma. It's also important to consider the longevity of the air filter.
Washable air filters are more expensive, but they should last for years rather than months. While this is a good idea in theory, it has several drawbacks such as a lower MERV rating, frequent maintenance requirements, and the potential for mold growth in the air unit. When it comes to air filter performance, all other things being equal, a filter with a higher MERV rating and more creases per inch will have the same or better airflow than the same filter with a lower MERV rating and fewer creases. Cheap air filters usually have a low MERV rating of 6 or less, while expensive air filters can have a MERV rating of up to 13. So, is it worth investing in a higher FPR filter? The answer depends on your individual needs and circumstances.
If you have allergies or asthma, then investing in an air filter with a higher MERV rating is likely to be beneficial. However, if you don't suffer from allergies or asthma, then you may be able to get away with using a cheaper filter. It's also important to consider the cost of replacing your air filter over time. If you opt for a washable air filter, then you may save money in the long run as you won't need to replace it as often.
However, if you choose a disposable filter, then you may need to replace it more frequently. Ultimately, when it comes to choosing an air filter, it's important to consider your individual needs and circumstances. Investing in an air filter with a higher FPR rating may be beneficial if you suffer from allergies or asthma, but if not then you may be able to get away with using a cheaper filter.
