Our filters for heating and air conditioning devices are distinguished by their unique manufacturing, all our filters are specially designed to provide you with an optimal level of filtration until the last days of use. For a long time, studies have been carried out in order to improve the quality of filtration of filters. In fact, it’s the MERV that determines the effectiveness of your filter. The higher the MERV, the more your filter will be able to filter small particles. When you buy filters, it is important that this filter is of good quality because it is the quality of the air in your home that depends on it. A good quality filter can significantly reduce the symptoms of asthma and allergies, especially in children.
The film of the heating filter is stuck on a metal grid to keep its perfect composition until its last use. The media is then introduced into a cardboard that is resistant to any formation of humidity to ensure a level of filtration that meets your expectations! Each part of the filter is sealed to obtain a dustproof seal. You can be sure that your filter will be effective.
Furnace filters sold in department stores have a much shorter lifespan than specialty filters, so you need to change them more often. It is very important not to neglect your filter as this can cause significant damage to your equipment. When you neglect your filters, the dust finds a way through the walls of your equipment and your filter then your ducts and your equipment collects dust in place of your filters.
If you order the wrong size filters, you will need to cover the shipping and handling costs for the items.
