MERV 4 Air Filters Review
MERV 4 Air Filter Overview
A MERV 4 air filter is the perfect choice for the frugal buyer who has no significant allergies or health problems. MERV means Minimum Efficiency Reporting Value and it shows the level of filtration an air filter provides, the higher the number, the more filtration.
A MERV 4 air filter may have a low rating but that does not mean that it is inferior. It simply means that the person who purchases that air filter does not need the extra level of filtration provided by filters with higher ratings. If that is the case then there is no reason to spend more money to buy a high MERV rating filter unless the situation changes.
Key Features of MERV 4 Air Filters
MERV 4 air filters provide good filtration of the following particulates:
- Dust mites
- Carpet fibers
Reasons to Purchase MERV 4 Air Filters
They are among the most inexpensive which makes them easy to replace because the spun fiberglass filters are cheap and disposable. Disposable filters are actually some of the most hygienic because all the dirt that builds up on them gets removed when the filter is thrown out.
Other types of MERV 4 filters are easy to clean since they can be washed. However, washable versions need to be dried thoroughly to prevent mold or mildew build-up. Since they are cheap, it is a good idea to buy two and rotate them during each cleaning.
MERV 4 air filters will help to save money since they do not tax the fan of the HVAC system in any way. An overtaxed fan can increase electricity costs because of the increased energy usage.
MERV 4 Air Filters Review: Conclusion
Not everyone needs an air filter that will offer maximum protection from airborne particulates. Anyone who is renting their home, does not have any significant allergies, and does not own a pet is a good candidate for a MERV 4 air filter. The filter will have to be changed every three months or so, but it can end up saving money in the long run, especially if those filters can be bought in bulk for a discount.
It should be noted that MERV 4 air filters are not a good idea for larger homes regardless of the health of the residents. A longer lasting, higher rated filter that does not need to be replaced as often is a better investment. If such a filter is unnecessary because of the purchaser’s situation then a MERV 4 air filter is the right choice for them.
