Insulation is much more efficient due to better seals, but that also creates an issue where contaminants and allergens can become trapped in the house and are continuously recycled through the house until someone breathes them in. This can cause various respiratory diseases and an overall decrease in the health of the household. <a href=\"https:\/\/www.galmicheandsons.com\/furnaces.html\">Furnace<\/a> filters are the best line of defense against these contaminants as they filter and remove contaminants and allergens from the system. This is why it is so important to keep furnace filters clean and to make sure you are using high quality filters.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Quality_Matters_When_It_Comes_to_Furnace_Filters\"><\/span>Quality Matters When It Comes to Furnace Filters<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>While trite, the old saying, &ldquo;You get what you pay for,&rdquo; holds very true for furnace filters. While you may be tempted to buy the least expensive or most basic filter, you should remember that furnace filters play a direct role in maintaining indoor air quality. Basic filters will protect you from large particles entering your lungs, but usually not from smaller particles including most allergens or irritants.<\/p>\n<p>For the best filtration, consider purchasing high efficiency furnace filters that have higher MERV ratings. Though you may pay more up front, it is hard to put a price on clean air and good health for you and your loved ones.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Get_the_Correct_Size\"><\/span>Get the Correct Size<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.galmicheandsons.com\/hvac-blog\/wp-content\/uploads\/furnace-filters-hero-2.jpg\" alt=\"Replacing Furnace Filters | St. Louis HVAC Contractors\" width=\"300\" height=\"229\" class=\"alignright size-full wp-image-924\" \/><\/p>\n<p>When replacing furnace filters, it is important to always check the owner&rsquo;s manual for the correct sizing specifications. A filter that is too large will not fit properly and could cause operating issues, while a filter that is too small will let unclean air pass by, compromising the indoor air quality of your home.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Check_Your_Furnace_Filters_Once_a_Month\"><\/span>Check Your Furnace Filters Once a Month<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>A general guideline is to check your furnace filter at least once a month. However, a number of factors such as the type of filter you are using and the contaminants that your home creates may require you to check more or less than that. If your air filter appears dark or dirty when you inspect it, it is time to swap it out.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Schedule_a_Furnace_Check-Up_Today\"><\/span>Schedule a Furnace Check-Up Today!<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>When it comes to indoor air quality and your health, it is always best to have the professionals come and check your furnace.
