House Air Purifiers Buying Guide

Customers shop for air purifiers at a home appliance store

Even though I mentioned a few whole house air purifier products that I considered as best in my opinion, it does not mean that you should buy any of them. You can look for other products that make sure that you have clean home hair and suitable for your home. To guide you on deciding which to choose among the house air purifiers in the market, I list some of the pointers that you can consider.

These considerations include knowing the advantages of a whole house air purifiers, different types of air purifiers, house air purifier best size to buy, and other features you can add.

Whole House vs. Portable Air Purifiers

You can argue that most homes like ours have an HVA system that resembles a giant air filter that eradicates many airborne particles and contaminants for clean air. However, this filtration system does not filter enough to get rid of these contaminants by 100 percent. These larger particles can cause allergies and other health problems in the family without the use of purifiers.

Even though your home has an HVAC purification system, expect that there can be bacteria residing in your air vent and return air duct, which contaminates the air quality of the house. Even if you argue that your home is clean, there is no guarantee that your house air is free from bacteria and airborne particles that can cause allergies and other health issues.

Therefore, using an air purifier provides an additional way to ensure clean air in our house.

There are two types of air purifiers that you can use in your home. These are the portable units and the whole house air purifiers.

It does not mean that one is better than the other. These types have their pros and cons. You only have to choose which one will provide the best indoor air quality and most suitable for your room or house.

First, let us talk about the portable units  ones.

  • Portable air purifiers

These air purifiers are small enough for versatile use. Because of its size, we can carry them in any areas of the house, which include your room and kitchen. We can also place them in a corner or on a table.

Moreover, these small air purifiers are energy efficient. We can place them in areas where there are a lot of particles to filter, such as a kitchen or pet room, to get rid of the pet dander.  These options are also affordable.

Therefore, this type of air purifier only works best in a small house or for personal use in your room.

  • Whole House air purifiers

This type of air purifier is built-in and works along with the HVAC system if it is filter-based. If the house purifier is return air duct-based, the installation of the purifier is directly along the path of the air duct system.

This type of purifier ensures that your whole house will have clean air free from airborne particles.

The main con of this type of air purifier is that it only works when the HVAC system is running. Therefore, you should run it all the time.

Different Types of Air Purifiers

A customer shops for air purifiersBecause your HVAC system is not enough to provide air purification system protection against particles that cause allergies at home, having an air purifier at home should be an investment. It can either be a portable purifier or for the whole house use.

Before you learn how to buy the best whole house air purifiers to make sure that you have clean indoor air, learn the different types of air purifiers based on filters and installation.

This knowledge is vital so you can choose which will work best for your home and indoor air quality purifier reviews. This information will also give you the right insight and expectation that air purifiers can filter particles the size of lesser than 3 microns.

  • Ionic

If you are looking for a quiet best whole house, air quality is the best choice. It is a silent air purification device because it has no motor.

How it works is that it filters using negative ions. Its negative ions bind with airborne particles with positive charge ion, resulting in them becoming denser. Thus they will fall from the air.

Yet, this device does not remove odor, and some models require maintenance.

  • HEPA

HEPA air filter is one of the best house air purifiers and the most popular in my opinion because it can remove several types of particles by 99.7 percent. It removes dander, pollen, dust mites, and mold spores. It is famous for home use because it improves air quality.

Meanwhile, this type of air cleaner requires maintenance by replacing the HEPA air filter every month. Also, it cannot trap bacteria, which are smaller than 0.2 microns and can cause allergies.

  • Electronic

The electronic type of air purifier filters particles by working with air conditioning or furnace filters. It makes use of electricity and HEPA filters for trapping contaminants. It can filter 99.98 percent allergens.

You need to ask a professional for its installation. It also requires maintenance like cleaning the air the collector cells and ionizing wires to ensure the best whole house air quality.

  • Ultraviolet

The ultraviolet air purifier makes use of ultraviolet light to improve indoor air by removing particles and bacteria that can cause allergies. It is small enough to fit in any parts of your home, including your room.

However, this type needs bulb replacement each year depending on the model to ensure clean house air quality.

  • Central(central air)

The central type allows whole house air purification system by connecting it to the primary cooling and heating systems of your home. It efficiently removes particles and bacteria.

For me, it is one of the products that provide the best whole house use. Aside from its ability to improve indoor air quality, it also extends the life of your heater and air conditioning by filtering the harmful particles that can damage them.

Meanwhile, this type of house air purifier needs professional installation.

  • Activated Carbon

The activated carbon filters are one of the house air purifiers that not only filter particles but also eliminates odors and gasses for improved indoor air purification system. It makes use of activated carbon filters filter and true HEPA filter.

It is an ideal choice for those who want to get rid of contaminants and unpleasant house odor. However, it is not efficient enough to eradicate dust and pet dander unless the model makes use of HEPA filters.

  • Air-to-Air Exchangers

From the word itself, exchangers are air purifier that cleans the air by exchanging the stale air to the healthy house air. Aside from this benefit, they also regulate the temperature and humidity in your home(whole home air purifier).

It is ideal for places with poor house air circulation. For me, it is the best choice for those in the areas who live in an environment with extreme temperatures.

Identifying the Best House Air Purifier to Buy

Airmate air purifiers are displayed during the Appliance World ExpoTo determine the best whole house air purifier reviews, you need to consider some factors that include the placement of the device in your home, the size of your house, and the whole house air purifier ratings.

When you are out shopping for your house air purifier, you might notice that some devices have ACH and CADR ratings. Now, you might be asking what these ratings are.

Although not all house air purifiers have these ratings, these are something that you should not overlook if you want the best whole experience with your product.

  • ACH

The ACH means ‘air changes per hour.’

It comes with a number rating such as 4X, 5X, or more to indicate the efficiency of a house air purifier. It shows how many times air purifiers exchange stale air with fresh air in a room.

A higher number means that it is better. It is because this number indicates how distant a whole house air purifiers can handle. For example, a full house air purifier can cover a room with a 300 square feet space.

  • CADR

The Association of Home Appliance Manufacturers developed this rating, which stands for ‘cleaning the air delivery rate. This rating indicates how large a whole house it can handle.

The CADR comes with numbers from 10 to 450 in three sets. The first set refers to dust, second for tobacco, and the third is for pollen.

The dust, tobacco, and pollen are the primary contaminants that the CADR rating measures. The higher the number is, the more effective the house air purifier is.

This information leads to one conclusion that to buy the best whole house air purifier reviews, you should measure the space of your room or entire home first in square feet.

To measure the space of a single room, measure the width and length in feet. After that, multiply them to get the result in square feet.

To measure the space of the entire home with multiple rooms, compute the total area for each room, as indicated above. This time, add the results to get the measurement of your home.
