Air Filtration in St. Louis

How Do Home Air Filtration Systems Work? 

Along with regular air duct cleaning and maintenance, a whole-home air filtration and/or purification system is your first line of defense when it comes to improving the indoor air quality of your home or business. 

While different types of air filtration systems operate in different ways, these systems generally perform the following functions: 

• Internal fans pull air from inside your home into the system
• Air moves through a series of air filters and/or purifiers that work to catch and remove various airborne particles, irritants, and pollutants
• Filtered/purified air is then circulated through the home 
• The process is repeated, with more airborne particles removed over time 

Most contemporary whole-home air filtration systems are effective in removing up to 99+% of airborne particles, contaminants, irritants, and pollutants, including dust, pollen, bacteria, and pet dander. These systems are typically installed directly into your existing heating and air conditioning system, where they work seamlessly with your HVAC to provide exceptional results without taking up excessive additional space in your home. 

What Are the Different Types of Air Filtration Systems? 

There are multiple different types of whole-home air filtration systems, each of which utilizes one of several different types of air filters. 

Some of the most common types of air filters include: 

• HEPA Filters: High-efficiency particulate air (HEPA) filters are capable of removing up to 99.97% of unwanted airborne particles, including various allergens and pollutants. Most HEPA filters have a minimum efficiency reporting value (MERV) rating of about 16, meaning they are capable of removing particles as small as 0.3 microns, including certain mold spores, bacteria, tobacco particles, and dust. HEPA filters are highly effective at trapping and removing large particles, such as pet dander and pollen, and are very cost-effective, making them an ideal solution for many home and commercial property owners. 
• UV Filters: UV filters utilize short-wave ultraviolet (UV) light to target and kill harmful bacteria, mold, and viruses. As air passes through the system, UV light disinfects and purifies it before circulating it through the entire home or building. One of the main benefits of these types of systems is their ability to eliminate harmful pollutants that can lead to various respiratory illnesses and diseases. However, they are somewhat less effective in removing larger particles, such as dust, from the air. As a result, UV filters are often used in combination with other types of filtration systems, which may include HEPA filters. 
• Electrostatic Filters: Electrostatic filters utilize paper and/or cotton fibers to create static. This works like a magnet for larger airborne particles, including dust, pollen, and pet dander. Electrostatic filters are particularly adapted to remove allergens, making them an ideal choice for people who have indoor pets, as well as those who suffer from allergies or have a family member who suffers from allergies in the home. Electrostatic filters can also be reusable or disposable, so you can accommodate your budget and environmental concerns. 

Other air filter options include washable filters, media filters, spun-glass filters, and pleated filters. The best air filtration system for your home will depend on your specific needs. Some are designed to remove allergens; others are made to kill harmful bacteria and mold, and still others help remove unwanted odors and irritants. You’ll also want to consider things like cost, maintenance, and ease of installation when it comes to selecting an air filtration/purification system for your home or business.
