What else do I need to know about whole-house air purifiers?  

Upon deeper research, you will discover that to achieve improved air quality in your house, you may need to install a complete HVAC air purification system.  This will ensure perfect air quality in every part of your house. However, it is important to note that this kind of system may require being built directly into the duct work of your house’s HVAC (Heating, Ventilation, and Air Conditioning) system.  

There are generally a couple of types of air purification systems that can be built into the duct work of your HVAC system namely:

- Return Air Systems

- Supply Air Systems

Return Air Systems

These allow the air inside your house to return to the HVAC system for heating or cooling to maintain the proper temperature in the home.

Supply Air System

This system is set between the furnace and vent within the HVAC system and filters the air that comes in before it is released back into the different parts of the house.

Both of the above filters need periodic maintenance about every 3-6 months depending on how dirty the air inside your house is. The filters are relatively cheap and while they should be installed by a professional, they are easy to install and maintain. You may want to set up a timetable for the maintenance to keep the good air quality flowing. The goal is to avoid instances where your filter gets clogged due to residue overload. Actually, it can get so clogged up that it even ends up expelling air pollutants back into your house thus defeating the purpose altogether.

Features You Must Consider for a Whole House Air Purifier

The quality of air in your house will be determined by how keen you are on detail. There are many features to be considered while you are purchasing an air purifier for your whole house. The focus here is to get good air quality by getting the best purifier your money can buy. Let's explore some of the features you must consider as you choose which purifier you will purchase for your house.

1. Hepa Filter (High-Efficiency Particulate Air)

 The major purpose of a HEPA filter is to remove polluted air particles from indoor spaces. This filter is known to remove up to 99.95% of airborne particles as small as 0.3 microns.

The HEPA filter can effectively rid your air of dust, pollen, allergens, bacteria, pet dander amongst other particulate matter from your entire house. This filter will save you from allergic reactions and other air-borne irritants especially if you have a history of allergies to dust.

However, it is important to note that a HEPA filter cannot remove gaseous pollutants and that’s when the Activated Carbon filter comes to play.

2. Activated Carbon Filter

This filter is used to supplement the other filters in a purifier and helps remove household odors and gases. There is no single standard as to how this particular filter should work because there are various standards available.

The recommended carbon filter is made up of fine granular particulate because it is most effective with odors and gases when compared to its organic counterparts.

3. CADR (Clean Air Delivery Rate)

While checking out the CADR of a filtering device, you should know that the higher the rate, the faster the device’s ability to clean the air in your house. CADR is a measure for the volume of purified air that passes through an air filter in a measured period of time.

4. Certifications and Online Ratings

Ratings are a good way to find out other peoples experience with a particular product. They can help inform your decision on whether you should pruchase a n air purifier or not.You will be able to find out if they were satisfied with the product.

5. Cost Of Replacing Filters

Most air purifiers have to be replaced every 3-6 months of usage depending on how clean the air in your house is. This means that you are going to incur some costs in every such period.

You should therefore choose an air filter with affordable filter replacements so as to keep your maintenance costs low and affordable. You can also consider purchasing a purifier that has recyclable (washable) filters to minimize costs fully.

6. Durability  

Check the warranty of your chosen item to ensure that it is long-lasting.  An item that has a warranty of more than three years usually has the capability of lasting double those years. Always ensure to purchase items with a warranty so that you are assured of a refund or free repair or product replacement in case your filter gets issues right after you purchase it.                

7. Noise Level

Good sleep is a good. You don't want to subject yourself to a loud annoying sound of an air purifier. This is why you must make sure to find out the noise level of an air purifier before purchasing it for your house. Try to choose a filter of not more than 40db (operating noise of a refrigerator) for your house. It is important to also note that the sound level of your purifier may be received differently depending on how you choose to position it.

8. Air Changes Per Hour (ACPH).

This refers to the amount of air added to or removed from a space per hour. The volume of air that has been filtered each hour, in this case, is the ACPH.  Air purifiers that offer 3 to 8 changes per hour will provide high quality clean air to your entire home.  You should always factor in an air purifier's ACPH basing on the amount of space that needs clean air.

9. Ozone Emissions

While some may argue that air purifiers with ionizer technology work better to remove certain air pollutants, research shows that inhalation of ozone emitted by ionization can lead to lung infections like; irritation, throat soreness, and chest pain overtime.  Instead of eliminating threats to your respiratory system, therefore, a purifier with ionizer technology may instead bring about respiratory diseases to you and your family instead.

10. Power Consumption

Watts are a measurement of power. If a purifier uses 40watts, every time it is switched on, that directly translates to a certain amount of money added to your electricity bill. Purchase a purifier with minimal wattage especially if you live in urban areas and intend to keep it running twenty-four seven.

You have collected all the information you need to Identify the best air purifiers for the entire house. You also have small pointers on what you should be looking out for as you consider a purchase.

We hope that you can follow our guidelines and choose any of the purifiers that we have listed that suits your needs and preferences.
