The pre-filter works with large particles like hair, dust, or micro-mesh materials. Meanwhile, the Max2 filter is confirmed to combine both true HEPA filter and activated carbon filter in one for doubled efficiency.
Even more, the machine comes with excitingly advanced features to enhance the user-friendliness, such as the Instant Air-quality Indicator LED, the dual-sided suctions, convenient remote control, eco mode, and quiet mode even at the highest settings.
The only drawback remaining is the expense of filter replacement.

4. LEVOIT Air Purifier for Home Allergies and Pets
At a glance, the LEVOIT 24db Filtration Core 300 is quite small to call it a whole house air purifier. This is partly true because this machine does come in a portable and minimalistic design.

How to Choose The Best Whole House Air Purifiers?
As we mentioned earlier, using a whole house air purifier is often expensive – in terms of the system, extra on installation and maintenance, as well as the power consumption.
Thus, you need to carefully read the buying guide, as follows, to make the most out of your budget.
Installation of Whole House Air Purifiers
The very first factor to take in mind is your house.
Air purifiers come in different constructions and with various technologies. Nonetheless, almost all of them are installed in a ceiling or a wall. Choose one based on the available space and your preference in the airflow.
- Wall air purifiers: This type is the most common for small houses. They are easy to install, control, and maintain. However, that the equipment is fixed in place makes it less efficient.
- Ceiling air purifiers: The ceiling-mounted air purifier systems are recommended for large houses or workplaces because they distribute pure air better. However, installation and maintenance are more challenging. The ceiling whole house air cleaners also consume more energy.
Sizes and Coverage Areas
Now that you make a choice of the wall- or ceiling-mounted units, the next question is the size. For a whole house air purifier, the capacity must be handled with the air space in the house or in the large room you use the purifier in. Meanwhile, the size should still compact for easy installation in the wall or ceiling.
Ways to measure your home:
- Use a tape to measure the length and width (in feet) of every connected room within the home space
- Multiply the measurements of each room separately.
- Add the results to figure out the total coverage area.
Types of Filtration
We mostly suggested filter-based machines because they do not create by-products during the filtration process.
Yet, not all filter-based units are the same. Accordingly, you can choose among:
- Flat-fiberglass filters: Made of layered fibers, the filters are expected to be both inexpensive and durable over time. In terms of efficiency, the filters can remove bacteria, dander, viruses, dust mites, and larger airborne particles.
- Washable filters: As the name suggests, these filters are reusable upon proper maintenance. They are often made of metal or plastic frames and additional polypropylene layers. The disadvantages are the low MERV scale at 1 to 4 only. Moreover, the filters possibly attract mold since they take a longer time than usual to dry.
- Media filters: These filters are used to trap sizable particles, rating from 5 to 13. Simply put, it works like a lint trap of the dryer. In drawbacks, the media filters are not very effective for microscopic particles. Moreover, you need to replace the filters once every several months to ensure air quality. Such an extra cost!
- HEPA filters: So far, these HEPA filters have been proven to best control the air quality as they can block over 99% of all particles. The efficiency rating is up to 17 to 20, meaning a significant improvement in the indoor air quality. Nevertheless, you should maintain and replace the HEPA on a regular basis. Otherwise, it will cause pressure and strain on the HVAC system.
- Electronic filters: Containing an electrical field, the filters attract and trap harmful particles like magnets. They require HVAC modifications to improve efficiency.
- UV filters: These advanced filters are to treat stubborn bacteria and harmful particles at once. They are common in nursing homes and hospitals.
Costs and Energy Consumption
The expense of a whole house air purifier itself depends on various factors, especially the types of filtration. For example, a HEPA unit might cost $1000 and the annual filter replacement possibly costs an extra of $70.
Plus, take the installation and maintenance cost into consideration. It would be better to choose reliable brands who are willing to support you with installation and warranty.
Another major cost is power consumption. Choose purifiers using advanced energy-efficient technologies to save the running costs.
The ACH Rate
The air changes per hour (ACH) rate indicates the number of times that purifier will get rid of the dirt and polluted air. The higher, the more effective. It also means that the purifier must work more and consume more power at the same time.
For that reason, you do not always need a very high ACH rate if the air quality in your area is not too bad.
Compare the cost and make a wise choice.
Additional Bells and Whistles
If the price is not your main concern but the air purification capacity, then consider advanced features like the activated carbon filters, ionizer, or wifi capabilities.
Combined with the True HEPA filters, the carbon filters can extract components that the HEPA filters might miss such as odors, damp smell, floating chemicals, and gases.
Meanwhile, the ionizer is in place to boost the purifying process by removing negatively charged ions. Also, it adds weight to the particles so the pollutants get sucked in the filter or fall into the ground.
More excitingly, some modern whole house air purifiers come with wifi connection to control the machine on your smartphone or mobile devices.
How Does The House Purifier Work?
Except for the dimensions and the installation, household air purifiers work similarly to other filter-based units. The particles will be sucked and trapped when floating through the filter.
Moreover, the whole house air purifiers must work with your residential HVAC (heating – ventilation – air conditioning) units. For example, on running with the cooling system, the purifier will filter the air, allowing it to pass through the cooling mechanic before passing the pure cooled air into your house.
Do home air purifiers really work?
You might think the indoor air quality is still good. However, there are millions of bacteria and viruses which are 10 times tinier than cells. It means you CAN’T figure out those harmful particles with your bare eyes and intake them into your body.
Using a home air purifier, you can rest more assured because the system will:
- Reduce pollutants in the air
- Take the fight to the sources of allergies
- Get rid of the annoying molds and odors in the house
How much does a whole house air purifier cost?
On average, the cost of a medium whole house air purifier system is ranging from $500 to $2000, not mentioning the installation, maintenance, and the periodical replacement.
Meanwhile, the cost of additional services can add up the whole house purifiers to $1000 and $5000.
Such an expensive investment! – But bear in mind that, your family’s health is priceless and worth it!
Should an air purifier run all day?
An air purifier is hot, but over is not!
Most experts confirm that you can safely run the system for around 12 hours per day. It will protect your pocket from a broken situation, meanwhile, the air purifier is not overused.
In case you still want to run the machine all day, you should use high settings for quick filtration and circulation in peak hours and reduce the setting for quiet operation at night or when you are out.
How do you install a whole house air purifier?
It is based on the types of whole house air purifiers you choose: the wall-mounted or the ceiling-mounted units.
If you have experience with the large air purifiers before, it is easy to follow the installation guide or tutorial videos. Otherwise, we suggest having professionals complete the task for you. The installation of the purifier, as we mentioned, is related to the household HVAC system. It might be a bit complicated.
Again, every household should have an air purifier for the family’s sake. The best whole house air purifiers are at your fingertips to choose from.
Nonetheless, it should not be your first line to defend the indoor irritants. The better practice is to minimize your carbon footprint, both indoors and outdoors, such as lighting candles, smoking, burning woods, etc.
Instead, have some small plants in the house and clean rooms frequently to get rid of mold and odors.
