How much does a whole house HEPA filter cost?

It’s estimated that on average most people spend a large chunk of their time indoors. Therefore, it is important that the air within the house is well taken care of.

Whole-house HEPA filters are easily available and fro the service they provide and how long they last, these filters are quite affordable.

Also, their price is determined by several other factors that are important to consider to ensure that you get the best whole house air purifiers for your house.

How to Test Air Quality at Home

How much does a whole house HEPA filter cost?

To purchase whole-house air cleaners you’ll spend anything between $1,000 to $5,000.

Do all homes have air filters?

Every central heating and cooling system requires an air filter. However, tracing the filter in some HVAC gadgets can be an arduous task.

Often, the air filter is situated in the blower or the return air duct compartment just before the return air gets to the air handler. This enables the filter to purify the air penetrating through your house just before it makes its way to the HVAC unit.

Features to Consider When Buying an Air Purifier

Factors that influence the price of a whole-house HEPA filter system

1. Type of filter

There are several types of filters and each of them costs differently. The first type of whole house filter available is the ultraviolet rays filter.

This type of filter is often found in hospital for its effectiveness in cleaning the air even of extremely tiny and invisible particles and disease-causing agents. It is often found inwards in which those affected by respiratory problems are admitted. For its niche market and effectiveness, this type of filter system does not cost the same price as others.

The other common type of filter is the electric air filter. As its name suggests, it requires electricity for it to work. It is a highly effective air purifier system for the home.

Flat filters are made of fiberglass. They purify the air by trapping dust but have a deficiency in cleaning and capturing even smaller particles. They are quite basic and need regular changing.  Monthly changes are recommended. As such, they cannot be that expensive.

Extended media filters ran on electromagnetic charge and are highly effective air purifiers for the whole house.

2. Hiring an expert

Many people love DIY projects as they provide an opportunity to learn something new and to save money.

However, whole-house air filter systems need to be installed by professional technicians. Getting them to help you install them is an additional cost above buying the system which affects the final price of your air filtration system.

3. The size of your house

Whole-house HEPA filters prices are determined by how big a house they can serve. Bigger houses require larger filters which are more expensive compared to the smaller filters required for a smaller space.

4. Brand names

Like with all household electronic equipment, whole house filters are manufactured by a lot of household goods manufacturers under different brand names.

Depending on the market, and the reputation of the manufacturer and brand, different brands have different prices.

More reputable brands known for high-quality products are slightly expensive than other brands that do not have similar market reputations.

5. Time to replacement

Whole-house air purifiers need to be changed regularly to ensure that they keep the air in your house at high levels of purity. The flat filters, for example, need to be changed every month although so many people ignore this fact thus endangering their lives and those they live with by breathing in poorly purified air.

Filters that require replacement often are usually highly affordable and pocket-friendly and easy to install.

With all these factors at play, the price of the whole house HEPA filter will vary.

Different experts estimate that considering the different factors, households spend between $500 and $6,000 on a whole-house HEPA filter.

On the lower end, households may have smaller houses and may prefer to use the filter that is changed regularly for its price friendliness while ignoring efficiency and effectiveness. While on the higher end, they may have much larger houses and the financial capacity to acquire the latest and most superior in whole house filter brands.

In addition, more expensive filters have been identified to be more effective in their service and last longer with little maintenance or changes.

How much do air purifiers cost to run?

Air purifiers are electronic equipment that most of the time are not seen or heard. They work quietly in the background to ensure that the air quality in your home is up to standards and that all air pollutants do not get an opportunity to enter your space and cause you respiratory diseases and allergies.

As a result, therefore, we can say that purifiers help us save on medical expenses that we would incur if we did not have them in our homes.

Factors that affect the cost of running air purifiers

1. Consumption and cost of power

One of the major costs of running electric appliances is their consumption and the cost of power units.

Where electronic products consume much, they tend to be highly costly to maintain and run. If the cost of power is also high, it is expensive to run and maintain.

Conversely and especially for air purifiers, their consumption is quite low and are therefore quite friendly to the pocket in terms of running costs. Manufacturers of these items understand that they will be used for part of the day. As a result, air purifiers are made to be highly energy-efficient.

This means that they consume very little electricity for every hour they are on, compared to other electronic equipment.

2. Type of air purifiers used

Maintenance and running costs for different types of air purifiers varies. For example, flat filters and extended media filters may not need any running costs but require lots of money to replace the filter every month or two.

3.  Maintenance-free filters

There are certain filters that do not require maintenance. These filters ensure that it is easy and simple to buy and install your filters into your house and change them only on the day that the fill up with dust particles or their day to replace has finally come.

4. Need for air purifier

Purpose of air purifier is another factor that one considers when it comes to purifier running costs.

For example, if the purpose of your purifier is to eliminate odors, then you will use an ozone purifier that is different from the UV light purifier and therefore has different maintenance costs.

5. Time of running the purifier

Another factor that goes into the cost of running whole-house purifiers is how long you leave it on. Is it on for 24 hours every day or for a few hours? This leads to increased running and electricity consumption cost when it is on for longer hours.

Users can try and use it for a few hours to ensure that they save on running costs.

Having considered the factors that affect the cost of running whole-house air purifiers, it is important to know identify how much it costs to run a filter.

As already mentioned, whole-house air purifiers are highly cost and energy-efficient and their monthly running costs are quite negligible. You do not even notice that you have an additional electrical component that is on for most hours of the day when your electrical bill arrives.

Therefore, households and families should not be afraid to acquire a whole house purifier on the fear of running and maintenance costs. They are pocket-friendly and help you to improve the quality of air that you breathe while you are at home, enhancing your health and that of your family members.

Regular replacement costs are the most common expenses and costs that you will incur when it comes to running whole-house air purifiers.

How long should you run your air purifier?

We breathe all the time and no one would like to breathe in air that is contaminated with disease-causing germs or other allergens.

When people buy air purifiers, they do it to ensure that they have pure hair in their households. It is therefore wise to ensure that the air purifier is running while you are at home. If you are afraid of the electricity cost, you can always switch it off during the periods when no one is home and switch it on when you are back home.

Ideally, whole-house air purifiers are meant to run for long, usually at least eight to twelve hours. When used like this, one is guaranteed of high-quality air levels in the house for longer.

Short use intervals lead to incomplete air purification as the presence of pollutants in the air is always entering the house at all times through wind, people’s activities and pets.

The following factors enable you to gauge how well you are using your air purifier. For most people, overnight use when they are in the house helps improve the quality of air and time of interaction at home.

Factors that affect decisions on how long to run an air purifier

1. Household electricity cost

Household electricity cost is the major impediment to having your air purifier on for 24 hours which is the ideal. As discussed earlier, this should not be a worry as air purifiers are highly cost and energy-efficient. As a result, their effect on the electrical bill is quite small and almost negligible.

They are cost-friendly and also highly energy efficient. I would highly advise to have it on at all times for better air quality.

2. Noise it makes

Like all mechanical and electrical appliances, the whole house air purifier must make a lot of noise?  The answer to this question is an emphatic no. Often the only thing you identify abut an air purifier is the fan spinning around in your house.

Often, the air purifier operates noiselessly without interfering with day to day life at home.

3. Your home schedule

If you are at home for only a few hours and would like to save on your electricity, it is advised that you can switch on your air purifier when you are home only. IT helps you breathe purified air in the house.

4. Opening the windows

IF you can open the windows to your house during the day, then it is better if you shut down the purifier for the day. Windows help improve air circulation within enclosed places which the purifier will also do. Running it while the windows are open may not be as effective as you would like.

5. How soon it needs replacement

IF you are running an air purifier that requires regular replacement, you can switch it on only for a few hours. This helps against having it filling up with debris and dust particles quickly thus prolonging its useful life and saving you the regular purchasing of new purifiers every time.

6. Time of the year

Different seasons have different air qualities. For example, during summer, the air is hot and dry providing proper conditions for germs to thrive. During this period, it is important that we use the air purifier longer to ensure that the air inside our homes where we hole up against the hot weather is pure and promotes good health.

7.  Brand of air purifier

Different manufacturers of whole house air purifiers provide different instruction on how to use their products. It is important that buyers follow the instructions on the user’s manual of the air purifier as specified by manufacturers.

Whole-house air filtration systems

Whole-house air filtration systems run through your houses’ HVAC systems.  In this way, the air that enters the house through the system is not only suitable for the house conditions but also highly purified for high quality and comfort while within the house.

Whole-house air filtration systems reduce the entry of allergens into the house and thus improving the quality of air breathed in the house and the health of the members of the household.

The quality of air indoors exacerbates allergic reactions and respiratory diseases. To prevent this from happening, the acquisition and use of whole-house air filtration systems are encouraged.

Hospital-grade air purifiers can also be used for the home. In hospitals, there are lots of sick people. The environment in the hospital must then be conducive for them to recover fully and not get or acquire other diseases and infections from the other sick people in the hospital.

Hospitals prefer to use ultraviolet air filter systems. This is because ultraviolet air filter systems have the ability to sieve out different pollutants and disease-causing germs.

2. Ultraviolet germicidal Irradiation

This type of air purification system is used for medical purposes but is also customized by air purification manufacturers for use at homes as a whole-house air purifier.

As it is based on ultraviolet rays, this purification system is used in hospitals due to its ability to destroy disease-causing airborne bacteria.

Advantages of using hospital-grade purifiers for the whole house

1. Kills disease-causing organisms

Ultraviolet ray purifiers and high-efficiency particulate air purifiers, when used at home, will be highly efficient in the capturing and the prevention of disease-causing organisms and bacteria from reaching the homes airs.

This keeps indoor air clean and the people living in that house healthy and disease-free.

This helps reduce the prevalence of allergens and other pollutants that cause respiratory diseases and allergic attacks and irritations from the house. Good health and a comfortable environment are the main reasons for acquiring hospital-grade air purifiers fro the whole house.
