High-quality air filters are made from superior materials compared to their cheaper counterparts. They are usually constructed from fiberglass, which is a porous material that can trap more dust and pollen than other materials such as cardboard or paper. You'll pay more for a washable air filter because it should last for years, instead of months. Although it may seem like a good idea, it has multiple drawbacks, such as lower MERV ratings, frequent maintenance requirements, and the potential to attract mold to your air unit. The consequences of a blocked filter go beyond causing problems with airflow; they also cause billing prices to rise.
When a filter blocks airflow, the system must solve the problem by increasing its energy production. This will eventually be reflected in your billing at the end of the month. The new filters avoid additional billing over time by allowing air to pass through them with the minimum required airflow. Air filters not only prevent the system from clogging up with dust and dirt, but they also clean the air in your home. FilterBuy offers more expensive air filters for one reason: they are worth it because of their quality and convenience.
When the MERV rating of a filter is too high, then the mesh fabric starts to constrict air flow. Here at Filter King we offer affordable filters that look expensive but provide protection equal to what you pay for. Dirty or clogged filters are never good for your system, and if you choose to use an expensive air filter instead of a cheaper one, it can be quite costly. Fine dust and dirt particles accumulate in the heat exchangers and cooling coils of the oven, blocking the flow of air. Washable air filters will save you money in the long run, since you don't buy replacement filters, but you won't save effort.
It turns out that both ovens and air conditioning units use the same filters and perform the same functions. Different filter materials have different MERV ratings because they have different abilities to protect against particles. It's strange that HVAC technicians recommend cheap fiberglass filters to people who don't remember to change them. HEPA filters filter bacteria and viruses and are worth the extra money for people with respiratory conditions such as emphysema. You want to make sure your home doesn't pose any kind of danger to your residents, and higher-priced filters offer greater protection. You may have read elsewhere that pleated filters restrict airflow, leading to a harder working oven or air conditioning unit that increases your energy costs and burns out the engine.
Expensive filters may seem like a luxury, but their role is too important to settle for lower quality filters. While a higher MERV rating seems better at first, know that it may not be the best for your specific oven and air conditioning unit.
