Many Medina, OH residents are concerned about their indoor air quality. Fortunately, installing air purifiers and UV lights can freshen the atmosphere. These systems minimize pollutants and pathogens, making breathing easier for everyone, especially asthma and allergy sufferers. So, for cleaner air, which device is better? Below, we’ll explain how air purifiers and UV lights work and highlight their differences. We’ll also discuss how these systems complement each other to improve indoor air quality. With these insights, you’ll be able to select the right system for your needs.
Filter-Based Air Purifiers
Filter-based air purifiers are filtration systems that remove particles from the atmosphere. These devices work by pulling air through one or more filters that capture particles and let clean air pass through. They trap common allergens like dust mites, pollen, pet dander, spores, smoke, and germs that cause irritation and illness.
High-efficiency particulate air purifiers in particular can capture fine particles that pass through conventional filters, resulting in exceptionally pure air. Some air purifiers also use activated carbon filters to remove odors and harmful gases from the air. These filters can help to eliminate unpleasant household smells and harmful volatile organic compounds released by carpeting and paint.
- HEPA filters: These filters use dense, pleated fibrous mesh to trap microscopic particles.
- Activated carbon filters: These filters use high-porosity activated carbon filters to absorb airborne molecules and gases rather than solid particles.
- Ionizers and electrostatic precipitators: These systems turn negatively charged ions into dust, efficiently removing particles from the air.
- Photoelectrochemical oxidation: This process uses light-activated catalysts to destroy airborne pollutants.
Homeowners who want to install a filter-based air purifier can choose between portable and whole-home systems. Portable air purifiers are standalone devices that can clean the air in a small room or space. These units sit on your floor or table, plug into a wall outlet, and move around easily. They work best for targeting a specific area like a home office or bedroom.
Whole-home air purifiers integrate into the HVAC system and ductwork and distribute clean air throughout the entire house. These systems provide continuous, centralized, and highly efficient filtration. Some devices work by replacing standard HVAC filters with filters that trap finer particles. Other systems connect a dedicated unit to your ductwork and divert air through a HEPA filter. Typically, since these models are wired into your HVAC and/or electrical system, they must be professionally installed.
When deciding between an air purifier vs. UV light, the right device depends on your particular needs. For cleaner air in a small house, an apartment, or a single room, a portable unit may be best. Portable air purifiers also tend to be more budget friendly. If you live in a larger space or a highly polluted area or want total coverage, choose a whole-home purifier. These systems can also be especially helpful in humid areas with lots of pollen.
UV Light Air Purifiers
UV light air purifiers use ultraviolet light to kill or deactivate harmful bacteria, viruses, and mold spores. These units are not filtration devices, so they don’t remove particles from the air. This means they don’t remove pollen, dust, or gases from the atmosphere. Instead, they work by using UV light to damage the DNA within biological pathogens, preventing them from reproducing.
Most residential HVAC UV light air purifiers utilize minimum-strength UB-B light and/or stronger UV-C light to kill germs. UV-C light, which has a 200-280 nanometer wavelength, is particularly effective at destroying biological contaminants. Just like filter-based air purifiers, both portable and whole-home UV light air purifiers are available for your house.
- Standalone UV air purifiers: These portable, freestanding devices typically work by using fans to blow air past a UV light and back into the room. Some units also include traditional air filters for enhanced air quality.
- In-duct UV systems: These devices are installed in your ducts and work by exposing air to UV light as it passes through.
- Coil sterilization systems: These devices install within your HVAC system’s air handler and shine light on the evaporator coil. They operate continuously to deactivate any mold, bacteria, or organisms that grow in damp, dark environments.
Like filter-based air purifiers, portable UV light air purifiers tend to be best for people who live in small spaces or have limited budgets. Integrated UV light for HVAC air purifiers gives you more comprehensive coverage over a broader space.
Comparing Filter-Based and UV Light Air Purifiers
When choosing between a filter-based or UV light air purifier, consider which type will best address your specific air quality issues. Generally speaking, filter-based air purifiers are the best air purifiers for allergies. HEPA filters, specifically, are great for removing particles as small as 0.3 microns, plus pet dander, pollen, smoke, and spores.
Ridding your home of these airborne irritants can alleviate symptoms like sneezing, congestion, and itchy eyes. It can also help prevent asthma attacks. Activated carbon filters can help eliminate pet odors and VOCs that off-gas from household furnishings. These types of air filters can combat respiratory irritation and help household members breathe easier.
UV light air purifiers can be especially helpful for people with compromised immune systems who live in homes filled with germs. UV-C light can kill most bacteria as well as respiratory viruses like colds and flu. These air purifiers can also kill airborne mold spores and other dangerous pathogens. By killing biological contaminants, UV air purifiers can help reduce the spread of illnesses and infections in your home. UV lights can also prevent mold growth in your HVAC system, which can improve its efficiency and enhance your air quality.
Since filter-based air purifiers and UV air purifiers have complementary strengths, many homeowners choose to use both. Using separate devices together or installing a combination unit can effectively fill your home with clean, sanitized air.
Safety Considerations
One more thing to keep in mind when you’re choosing an air purifier is safety. Air purifiers should be harmless if you install and use them properly. However, some ionizing air purifiers can produce ozone, which is a respiratory irritant. Filter-based air purifiers also need regular cleaning so they don’t re-release contaminants into the air. UV air purifiers need proper shielding to protect people and pets from exposure to their light, which can be harmful. An expert HVAC technician can recommend an easy-to-use air purifier that will minimize any chance of danger.
