The Best Induct Air Purifiers – Consumer Reviews

Before we go into induct air purifier reviews, for the purpose of those who might not know, let’s shed light on what an induct air purifier is. In duct air purifier, also known as “whole home or in-line” purifier is a type of air purification system integrated into a home or office with existing HVAC ductwork.

Duct air purifier system does not simply filter air using HVAC internal air filter system. It is also effective in neutralizing dust, dander, dirt, pollen, and germs using the power of UV light and ionization technology, depending on the design of the product.

Do induct air purifiers really work?

Induct air purifiers are installed entirely within an office or a home’s ductwork, and they work effectively cleaning the air in the entire home. An in duct air purifier installed functions efficiently in eliminating 99.03% of viruses, 99.9% of odor, 98.85% of bacteria, and 78.85% of mold from the entire home and not just one area. This is because the HVAC system circulates all the air in the home.

Where is the best location to place an induct air purifier?

To get the most out of an air purifier, then it should be placed in the right and best location. Therefore you should consider the best location for an air purifier, especially when dealing with a portable air purifier. But for an in duct air purifier, the placement is not really an issue as you can install it into an existing HVAC system in the house. All you need to ensure is that it is located in a place in the duct, where the air circulating around the home can pass through it, and the airflow is highest.

Are induct air purifiers as effective as portable air purifiers?

The simple answer is yes, induct air purifiers are every bit as effective as portable ones, probably even more effective. Portable air purifiers are effective for small or single room areas, while an induct air purifier is effective not just for a single room or an area in the house but for the whole house purposes. However, in duct air purifiers require an existing HVAC system to function, while the portable ones do not.

How does an induct air purifier really work?

There are two basic types of in-duct air purifiers; one is UV air purifier and the other ionization air purifier. 

  • UV air purifiers

Just the way sunlight kills germs, they design UV air purifiers to replicate this process but in a closed and controlled environment using UVC and UVV rays to neutralize harmless particles passing through the air duct. Since air streaming through a home’s ducts has already been passed through a filter, we predominantly use this method in neutralizing germs, odors, and very little small particles that can pass through a common HVAC filter.

  • Ionization air purifier

This air purifier cleans the air by electronically charging air molecules so that they bind with positively charged particles, including dirt, dust, smoke, soot and pollen, and germs. Once they become heavy and fall on the ground or a nearby surface, they can be swept or vacuumed up over time.

  • New media filters

All furnace comes with a pre-installed filter designed basically to catch large particles in the air as they move throughout the HVAC system. An extended media filter is a thick set of special designs installed in-duct that enhances the filtration power of the existing system.

Factors to Consider in Getting the Best Induct Air Purifier 

  • Removal and collection of particles

HEPA filter air purifier is perhaps the most efficient air purifier at removing air pollutants and particles from the air in the house. So when considering the right induct air purifier, taking note of the filtration system and HEPA filters are always advisable.

  • Odor elimination

In terms of the best air filter for odor elimination, ozone purification, and activated carbon air filter are the best of the best. Ozone is extremely good at Killing bacteria that brings annoying odor, while activated carbon is good at absorbing odor

However, one should turn off the filter when not in use as excessive ozone is not healthy because it causes irritation and could have long term hazardous effects. All products with ozone must be under the recommended safe limit.

  • Ability to Capture chemicals, gases, and smoke

It is advisable to consider whether or not an air purifier can capture pollutants such as chemicals, gases, and cigarette smoke.

  • Ultra Violet Light

Ultraviolet light is actually very efficient when it comes to fighting and killing microorganisms such as germs, bacteria, fungi, and viruses. It is imperative that you confirm the efficiency of an induct air purifier in destroying microbes before purchasing 

  • Sanitation of filter

You should consider air purifiers with easy to sanitizer filters in choosing the best induct air purifier. Air filters may become a breeding ground for microorganisms since they contain fabric that enables microbes to attach themselves to the captured pollutants and then reproduce or breed through that medium.

So considering an air purifier easy to sanitizer is advisable. Also, a germicidal UV lamp effectively solves this issue, while an ionized or ozone generator may also be relatively effective.

  • Cost of maintenance

Maintainance cost is a very important factor to consider before purchasing an air purifier because most air purifier requires constant maintenance to function effectively. Buying and replacement of filters and bulbs should be done at least between 3 months to a year, depending on the manufacturer’s specifications. However, there are air purifiers that are very cheap to maintain but have poor performance.

  • Electricity consumption

Electricity consumption is another important factor to consider in choosing the best induct air purifier. The electricity bill can be quite alarming if using a unit that consumes a lot of power. So it is quite advisable to purchase an energy saving air purifier as it saves cost.

  • Noise level

Considering the noise level of your air purifier is quite advisable before purchasing. Some air purifiers can be so noisy it becomes so unconformable to use, especially those with filters. For Purely UV products, you would certainly have no issue with noises.
