Why Install a Whole-House Air Filtration System?

If you want to improve air quality in your home, then you can install individual air purifiers in different rooms. However, you can also use a single system that works in all your rooms. How does whole-home air purification work? Why should you install this type of system?

How Does Whole-House Air Filtration Work?

Whole-house air filtration systems typically sit inside HVAC ducts. You can install them when you put in a new HVAC system or retrofit them in some cases.

Some systems use filters. They usually pre-filter air to get rid of large particles, such as dust or dirt. This partly treated air then passes through finer HEPA or activated charcoal filters which capture tiny particles and deal with odors and chemicals.

Other systems use specialized disinfection devices to treat air as it passes through them. For example, some units use ultraviolet energy to improve air quality. This energy has proven abilities to sterilize air and deal with germs, viruses, and pathogens.

What Are the Benefits of Whole-House Air Filtration?

Individual air purifiers clean air in their immediate environment. However, they don't give all homeowners a perfect solution. A whole-of-house air filtration system has additional benefits. What are they?

Get Comprehensive Air Cleaning

Individual air purification units have limited reach. They can only clean air around them. They might not purify all the air in your home.

If you install a whole-home filtration system, then it treats all the air that comes into your rooms. It purifies circulated and recirculated air whenever it goes through your ducts.

Every room in your home benefits. Your HVAC system automatically dispenses cleaner and purer air from all its vents.

Plus, these systems work automatically. If you use individual purifiers, then you have to remember to turn them on, while whole-home systems work whenever you use your HVAC system.

Keep Allergens and Harmful Substances Out of Your Home

As air circulates around your HVAC system, it can pick up particles of dust. It can also carry other substances such as viral particles and pollutants.

If you have allergies or asthma, then the air in your home might not be good to breathe. It might trigger allergic reactions and asthma attacks. If germs, viruses, mold spores, or pathogens get in your air from outdoors, then your system might circulate them around your home and make you sick.

Whole-home air purification systems prevent these problems. Depending on the system you use, you can clean your air or sanitize it. The air you breathe will be healthier. You'll be better able to control your allergies or asthma, and you are less likely to pick up airborne illnesses.

Make Your Indoor Air Smell Better

Your HVAC system circulates and recirculates air. As it does this, it can pass odors through your home. For example, cooking smells can spread and linger.

If you use an HVAC-based air purification system with odor-busting filters, then your system removes smells from your air. Your air will smell cleaner and fresher.

Reduce Your Costs

Any air purification system has a financial cost. If you buy individual units, then you have to buy the units and pay for the energy they use.



While this might not cost too much in a small home, your costs could be high if your home is bigger. You will need to buy multiple units and pay their running costs.

Whole-home systems have cost efficiencies. Your system becomes part of your HVAC system. Filters don't need extra power to work; purification devices use minimal power.

Plus, air purification systems help keep HVAC systems in good working order. If you clean dust and particles out of your air, then you also keep them out of your ductwork and equipment. You'll have lower cleaning, repair, and maintenance costs.
