Hunter Air Purifier Filters - How Do They Work?


  Hunter air purifier filters come in a number of different forms to help make your home as clean and fresh as it can possibly be.

While Hunter will traditionally use two different types of filters to operate their air purifiers, you can determine which type is better suited for your own home. Hunter air purifier filters can come in many different types and prices and you will want to know the difference between the two before you make a purchase.

Both types of filtration system will expose the air to three different levels of purification.

The core component of these two types of systems will vary greatly, however. One of them needs a replaceable HEPAtech filter while the other uses a permanent PermaLife filter. Each of these filters will work to help trap and destroy contaminates in the air, yet will perform in vastly different ways.

Hunter Air Purifier Filters

First Stage of Filtration - Carbon Pre-filter

In both models, the air will be pulled in through the fan and move through an activated carbon pre-filter.

This filter is designed to perform two functions. First, the carbon in this filter will work to absorb up to 30% of the unwanted odors that may be permeating your air. This can greatly reduce the effect that cigarette smoke, pet odor, smells from cooking and other food, or even personal odors that may arise in any room. One should easily be able to notice the effect that this odor suppressant will have.

The second effect of the pre-filter is to trap the largest particles that will come in through the fan as part of the air filter. This will trap the pieces of hair, lint, and other large particles which may happen to flow through the air and enter the front grill of the purifier. The more contaminates that can be kept from the main filter, the longer that filter will last and the better it will perform.

The Second Filtration Stage - The HEPA and HEPAtech Filters And PermaLife filter

This will vary based on the type of Hunter air purifier filters that your unit will use. In either type, this is the main filtration stage that will remove the highest amount of particles from the air and work to make your air as pure as possible.

Both types of filter will remove over 99% of the particles from your air, making it a very effective source for air purification.

The first type covered are the Hunter air purifier replacement filters. These are the filters that you will need to change around every six months to a year because they will collect a large amount of particles and clog. These filters are traditional HEPA and HEPAtech filters.

HEPA filter

A HEPA filter uses a type of filter technology that will trap 99.7% of the particles floating through the air that are as tiny as 0.3 microns. This can work well to make sure that you always catching as many particles and contaminates in the air as possible. This filter will traditionally work on everything from dust to cigarette smoke, keeping the air clean. HEPAtech filters

HEPAtech filters, on the other hand, use the same type of filter technology but they are also given a permanent charge during the construction phase. This will end up attracting even more particles in the air. While it is guaranteed to trap 99.7% of the particles as tiny as 0.3 microns, the charge on the filter will often collect particles up to 0.1 microns small. This is the height of filtration levels of success.

Both of these types need a replacement HEPA filter for Hunter air purifier technology. A traditional HEPA filter can often last up to a year while a HEPAtech filter, due to its attraction quality, will often need to be replaced every six months.

These Hunter air purifier replacement filters can run from anywhere of $40 to $80. While this is often a costly replacement price, it is also the filter that works the best and collects the highest level of contaminates.

PermaLife filter

The other type of filter which is commonly used is that of a PermaLife filter. The boasting quality of this filter is that, if taken care of properly, it will never need replaced. Every few months, using a vacuum and upholstery tools, you will have the ability to clean these filters out and insert it, good as new.

This Hunter air purifier filter is not a HEPA filter, but it uses HEPA-like technology to remove 99.5% of the contaminates from the air that are as tiny as 0.5 microns. This can work to make your air very clean.

While it may not be able to remove as much from the air as an original HEPA filter, the fact that this filter should never need replaced can be a huge draw. Particles as small as 0.5 microns is still very efficient and consists of most of the contaminates in air.

Hunter QuietFlo 730 air purifier filters are an example of this type of PermaLife filter.

Third Stage of Filtration - The Ion Generator

  The final stage of the air purification process involves an ion generator. This function is optional on all of the purifiers but can help to freshen the air and make it much easier to breathe and process.

At this stage, as the air is exiting the purifier, the ion generator will introduce negative ions into the air. These ions work to freshen the air, making it seem as if you are enjoying the outside air without any of the allergens which are associated with that air. It can be a great option to make any room seem fresh and clean.

Hunter air purifier filters all work to ensure that you are getting some of the freshest, cleanest, most pure air that you can have.

While these filters will perform in the same basic manner, they each have unique qualities that will help to give you a different level of satisfaction. Knowing the qualities of these filters can help you make the right choice for your next air purifier.
