How Much Is a Whole House Air Purifier : Guide Before Buy

When it comes to ensuring clean and healthy indoor air, a whole house air purifier can be a valuable investment. However, determining the cost of a whole house air purifier involves considering various factors.

In this article, we will explore the key elements that influence the cost of a whole house air purifier. It provide you with a comprehensive guide to understanding how much you can expect to pay for this essential home appliance.

Factors – How Much is a Whole House Air Purifier

1. Home Size

The size of your home plays a significant role in determining the cost of a whole-house air purifier. Larger homes require air purifiers with higher capacity and coverage to effectively clean the air in every room.

Room capacity is a critical factor in selecting an air purifier

As the size and the capacity of the unit increases, so does the price of the air purifier also. It is essential to evaluate your home’s square footage and choose an air purifier that matches your specific needs.

In the installment process of the air purifiers, one of the practical factors that you need to concern about is CADR value.

CADR stands for Clean Air Delivery Rate. It is a measure used to evaluate the effectiveness of an air purifier in removing specific airborne pollutants from a room. The CADR value is determined through standardized testing procedures and provides consumers with a quantitative measure of an air purifier’s performance.

CADR is typically expressed in cubic feet per minute (CFM). It represents the volume of clean air that an air purifier can deliver. It is measured for three types of pollutants: dust, pollen, and smoke. Each pollutant is tested separately to assess the air purifier’s efficiency in removing that specific type of particle.

The higher the CADR value, the more effective the air purifier is at removing pollutants from the air.

For example, if an air purifier has a CADR rating of 200 CFM for smoke particles. It means that it can remove smoke particles from the air at a rate of 200 cubic feet per minute.

When selecting an air purifier, it is recommended to choose a model with a CADR rating that is appropriate for the size of the room in which it will be used.

The Association of Home Appliance Manufacturers (AHAM) provides guidelines on selecting air purifiers based on room size and CADR values.

It’s important to note that CADR values should be considered alongside other factors, such as the

  • Type of Filtration system
  • Noise levels
  • Energy consumption
  • Additional features are offered by the air purifier.

By considering all these factors, you can make an informed decision. You can also choose an air purifier that meets your specific needs for clean and fresh indoor air.

2. Filter Type

The type of filter used in a whole-house air purifier can also impact its cost. Different filters target specific pollutants and offer varying levels of effectiveness.

Common filter types include High-Efficiency Particulate Air (HEPA) filters, activated carbon filters, UV light filters, ozone generators, and ionic filters.

HEPA filters are often more expensive due to their superior ability to capture small particles and allergens.

HEPA Filter Air Purifier

HEPA filters are widely considered the gold standard in air purification. They can effectively capture small particles, including dust, pollen, pet dander, and mold spores.

Due to their high efficiency, air purifiers with HEPA filters tend to have a higher cost. However, they provide superior air cleaning performance and are highly recommended for individuals with allergies or respiratory conditions.

1.1 Budget Range:

In the budget range, you can find HEPA air purifiers priced between $50 to $150. These models often offer basic functionality, suitable for small rooms or limited budgets.

They may have lower CADR values, fewer advanced features, and a limited coverage area.

1.2 Mid-Range:

The mid-range HEPA air purifiers typically fall within the price range of $150 to $300. These models offer a good balance between affordability and performance.

They often have higher CADR values, enhanced filtration systems, and additional features such as multiple fan speeds, timers, and air quality sensors. They are suitable for medium-sized rooms and offer improved air-cleaning capabilities.

1.3 High-End Range:

High-end HEPA air purifiers can range from $300 to $1000 or more. These models usually come from well-established brands and offer advanced features, larger coverage areas, and higher CADR values.

They may include additional filtration technologies like activated carbon filters, UV light sterilization, smart connectivity, and customizable settings.

High-end HEPA air purifiers are ideal for large rooms, offices, or individuals with specific air quality concerns.

Activated Carbon Filter Air Purifier

Activated carbon filters are effective at removing odors, gases, and volatile organic compounds (VOCs) from the air.

They work by adsorbing these pollutants onto their porous surface. Air purifiers equipped with activated carbon filters may have a moderate price range, making them a popular choice for improving indoor air quality and eliminating unwanted smells.

UV Light Filter Air Purifier

UV light filters use ultraviolet radiation to kill bacteria, viruses, and other microorganisms in the air. These filters are often used in conjunction with other filtration systems and can be an additional cost.

While they provide excellent germicidal benefits, they may not be necessary for every household.

Ozone Filter Air Purifier

Ozone generators produce ozone molecules that react with and neutralize odors and pollutants in the air. However, ozone can be harmful to humans and pets if not properly regulated.

Due to their potential health risks, ozone generators should be used with caution and only in unoccupied spaces.

The cost of ozone-based air purifiers can vary, but it’s important to consider their limitations and potential drawbacks before purchasing.

Ionic Filter Air Purifier

Ionic air purifiers use ions to charge particles in the air, causing them to stick to surfaces or get trapped in a collection plate.

They are generally less expensive than other types of air purifiers but may have limited effectiveness in capturing smaller particles.

Ionic air purifiers are often chosen for their quiet operation and low energy consumption.

3. HVAC Location and Accessibility

The location and accessibility of your home’s Heating, Ventilation, and Air Conditioning (HVAC) system can affect the cost of installing a whole-house air purifier.

If your HVAC system is easily accessible, installation costs may be lower. However, if the system is challenging to reach or requires modifications, the installation cost may increase.

It is advisable to consult with professionals to assess the installation requirements and associated expenses.

4. Installation Cost

The installation process itself can contribute to the overall cost of a whole-house air purifier.

Some units can be installed by homeowners, while others require professional installation. Professional installation ensures proper placement and optimal performance of the air purifier but comes with additional costs.

If you are unsure about the installation process or have a complex HVAC system, it is recommended to hire a professional for installation.
