Filtrete 1900 Maximum Allergen Reduction and Filtrete 1900 Maximum Allergen are two of the most popular air filters on the market. In Auto mode, these filters reduce particles by 0.3 microns at 18.0% (ambient) and 26.4% (clean). In Silent mode, they reduce particles by 6.5% (ambient) and 7.2% (clean). And in Dark plus Auto mode, with its primary PECO purification system turned off and its fan at the equivalent of a medium setting, they reduce particles by 21.3% (ambient) and 18.0% (clean).
HEPA filters are a great choice for people living with allergies or other respiratory problems, as they are designed to capture particles as small as 0.3 microns. A contractor needs to adjust these filters to fit your specific HVAC system. UV filters use short-wave ultraviolet light to kill bacteria and viruses, but they are not as efficient when it comes to protecting against contaminants such as dust. That's why they're often part of a larger filtration mechanism, including HEPA air filters.
Electrostatic filters use small cotton and paper fibers to create static electricity that acts as a magnet for dust and other particles in the air. This magnetism is strong enough to prevent these particles from spreading throughout the house, making them one of the best options for those who need a filter that can combat allergens. Electrostatic filters are available both disposable and reusable, so you can decide whether to wash and reuse them or throw them away and buy new ones. Washable filters are an eco-friendly way to save money, as the starting price of this type of air filter for HVAC systems is high but it should be considered an investment that will last for many years.
Washable filters need to be maintained well to ensure they work as they should, so it is very important to ensure that the filter is completely dry before reattaching it. Media filters provide more benefits than standard filters with high MERV ratings, as they provide the same level of filtration without the negative consequences of airflow or static pressure. Media filters are very easy to maintain and ideal for filtering bacteria and other small airborne contaminants, while filtered dirt seals in the filter, preventing it from being ejected back into your home. A high-quality oven filter designed to filter small particles can remove many allergens from the air and provide a measure of relief for people with allergies.
This product's high MERV rating is close to that of an N95 mask, keeping your home air clean. The pleats of these filters give them an advantage over non-pleated options because they increase the surface area of the filter for better filtration. In general, high-efficiency filters that are also cost-effective are best for homes, but other considerations should include whether there are pets in the house, if mold is a threat, and how often filters need to be changed.
