Air Purifier Filters – Do You Want To Clean Or Replace?

Air purifier filters can have a huge impact on the choice of air purifier we choose to buy, as many of us do not wish to incur the time and expense involved with regular replacement of these air cleaning filters. As the effectiveness of your air cleaner is dependent on keeping it well maintained and running smoothly, it is wise to consider whether you want to deal with air purifier filters before you buy.

One of the most effective air cleaning technologies available today is that used in the HEPA air purification systems, said to remove 99.97% of particulates from the air. This type of air cleaner, however, employs special air purifier filters, which must be changed on a regular basis in order to maintain the system’s efficiency.

There are also air purifiers available which don’t need air purifier filters; electronic air purifiers do not require air cleaning filters to work. This system works by gathering particles from the air on collecting plates inside the cleaner, and while these do not require regular replacement, the filterless air purifier still needs some maintenance to remain at optimum efficiency – the collecting plates must be cleaned regularly.


The very job that air purifiers do – removing particles and dust from our air that we do not wish to breathe in – necessitates some maintenance, as these particles will gather within the cleaner and will need to be disposed of. But while both filterless systems and those that employ air purifier filters require some upkeep to remain effective, this is minimal in both cases. The job itself involves only the simple wiping down of collection plates, or quickly changing a filter – the problem is remembering to do it!

And once you establish the habit, this simple air purifier filter maintenance will become a part of your routine. So don’t allow the thought of changing air purifier filters determine your choice of air cleaner – choose the system that is best for your family, and remember that the small amount of maintenance that comes with any air purifier is worth the work. Better those particles on your air purifier filter than in your lungs!

7 Tips to Keep Your Air Purifier Cleaning Air Effectively

Including an air purifier as a part of your home can be a great way to make sure that you are always in the cleanest, healthiest environment possible. Depending on the model of purifier that you choose to purchase, you will be giving yourself the ability to do everything from removing all of the common allergens from the air, like dust, pollen, and dander, to potentially even ridding the air of airborne viral contaminates, like germs, bacteria, and mold spores. Of course, in order to keep your air purifier cleaning air effectively, there are a number of steps that you are going to need to take. Some of these machines can be somewhat delicate and if you don’t take proper care of them, they will begin to function in an improper way. This can lend themselves to breaking easily and this is not a desirable outcome. Therefore, these 7 steps can help you make sure that your room air purifier is always going to work to the best of its ability.

1. Change Filters Regularly

This step may sound obvious to many people, but unless you actually change the filters when they actually need to be changed, you run the risk of doing damage to your air purifier. The dirt accumulation will start to build up on your purifier and you can easily run the risk of causing damage from clogging. This isn’t even to mention the fact that a dirty filter will hold no level of cleaning power. All of the air that passes through it will not be treated at all.Some models will let you know when the filters need to be changed while others will make you manually check. The instructions to the unit should be able to give you a general indication of normal filter life, however. Make sure you follow the instructions provided to have the best functioning air purifier possible.

2. Clean the Units Often

On top of changing the filters, you should take steps to actually clean the surface of the unit. Dust, dirt, and other forms of grime can often build up on the machine. This can potentially clog the machine as well as the filters and not aid in you air purifier cleaning air effectively. Wiping the surface down with a damp cloth should effectively take care of this.

3. Vacuum The Room Often

The more dirt in the room that you use the air purifier, the harder it will have to work. If you vacuum the room often, you will be removing as many of the contaminates from the floor of the room as you can. This will help the purifier continue to operate at an optimal level for as long as possible.

4. Don’t Open the Windows

People typically think that the air from outside can do them harm. They view that air as fresh and pure. If you open the windows to a room you have been using your purifier in, however, you are doing two things. First, you are letting all of the air that you have been working on making fresh and purified escape through those windows and out into the world. Second, you are bringing in new air that can be filled with pollen and other allergens. Basically, you are making your air purifier start over from scratch. This won’t help the life of the unit.

5. Position the Purifier In an Open Area

Many air purifiers are built so that they can function when placed in a corner or up against a wall. While they will still function when placed in these areas, they will have the greatest access to air flow when placed in an open area of the room. Setting these purifiers out in the open, even just for small periods of time, will keep your air purifier cleaning air effectively as possible.

6. Run According To Your Needs

Many units will effectively change the air in your room many times in the course of an hour. Simply running your room air purifier at key points during the day can help your filter life to last much longer and still give you a safe, clean environment.

7. Protect Against Electrical Damage

A room air purifier is an electric appliance and runs on power out of the wall. Much like your computer, should you experience a power surge, you could run the risk of harm coming to your air purifier. For this reason, keeping your unit plugged into a surge protector could help protect against any unforeseen electrical damage happening to your motor.

Compare Air Purifiers – Ten Factors to Consider Before Purchasing One

honeywell50250airpurifier-1Most people narrow down their choices to two or three air purifiers before making a final decision. Use these ten factors to compare air purifiers head-to-head. Keep in mind that it is not as important that you are exact in using the rating factors, but that you are consistent ranking each purifier you are comparing. If you do not know the information needed to complete any of the ten factors below, do additional research on air purifier company websites, internet reviews, or informational websites. Make your best guess when all else fails. I encourage you to invest some time in this process. Many purifiers “sound good”, but when compared head-to-head with others, they fall short. Let’s get started!

1) Which Air Contaminants are Removed: An air purifier is only as good as what it removes from the air. There are six contaminant categories. Each category alone is important and when combined, they are the basis for any good overall air cleaning. The six categories are: Removal of Particles larger than 0.3 microns (examples: dust, pet dander, pollen), Removal of Particles less than 0.3 microns (examples: small dust, tobacco smoke), Removal of Odors and Gases (examples: food smells, chemicals, aerosols, pet smells), Removal of Volatile Organic Compounds or VOCs (examples: paints, varnishes, cleaning supplies, glues, adhesives), Removal of Basic Microorganisms (examples: viruses, antigens, pathogens, bacteria), and Removal of Advanced Microorganisms (example: Avian Influenza A). When you compare air purifiers, do your best to rate each purifier for each of the six categories: Good Removal, Fair Removal, or Poor Removal. Then, rank each purifier overall: Best Remover, Second Best Remover, Third Best Remover, etc.

2) Yearly Operating Costs: The initial price of an air purifier is only one factor in the total operational cost. Operational costs include consumables like HEPA and carbon filters, VOC cartridges, and UV lamps. Electricity consumption is also an operational cost. Do comparison research on the operational costs for each purifier. Consider averaging costs over a five-year time frame to get a more accurate long-term picture. After rating all the purifiers, rank them: Best Yearly Operating Costs, Second Best Yearly Operating Costs, Third Best Yearly Operating Costs, etc.

3) Value: To calculate the relative value of a given air purifier, consider several factors: total cost, square footage cleaned, and cleaning ability. Total cost includes purchase price plus yearly ongoing operational costs (use from #2 above). Write down a total cost dollar value for each purifier you are comparing. For square footage cleaned, your goal should be to buy a purifier that is size suited for the area you want cleaned. Write down a square footage for each purifier. Cleaning ability includes what is removed and how well (use the data you compiled in #1). The best value would be the purifier that costs the least, cleans the most, and removes the most. Rank each purifier: Best Value, Second Best Value, Third Best Value, etc.

4) Quality: Quality defines good products. Rate each air purifier for quality in these three areas a) fit, finish, and workmanship b) the quality of cleaning technologies utilized and c) support: instruction manual, customer service, and company websites. Rate each purifier: Excellent Quality, Good Quality, or Questionable Quality for each factor. Now, rank each purifier overall: Best Quality, Second Best Quality, Third Best Quality, etc.

5) Warranty: A good warranty generally shows that a company has faith in their products. When comparing, rate each purifier: 5-year or greater Warranty – Excellent, 3-4 year Warranty – Good, or 2-year or under Warranty – Fair. Rank each purifier Best Warranty, Second Best Warranty, Third Best Warranty, etc.

6) Maintenance and Cleaning: Almost every air purifier has some ongoing maintenance. Most purifiers are designed for easy maintenance. When comparing, rate each purifier: Easy Maintenance, Average Maintenance, or Intensive Maintenance. Almost every air purifier requires some ongoing cleaning. This may be as simple as wiping down the outside cabinet or as complex as cleaning the inside technology. When you compare air purifiers, rate each purifier: Easy Cleaning, Average Cleaning, or Intensive Cleaning. When done, rank each purifier overall: Best Maintenance and Cleaning, Second Best Maintenance and Cleaning, Third Best Maintenance and Cleaning, etc.

7) Look and Feel: How an air purifier looks is important. When comparing, rate each purifier: Looks Great, Looks Good, or has Questionable Looks. How an air purifier “feels” is also important. Key factors include: purifier controls, fit and finish, and ease of use. When comparing, rate each purifier: Feels Great, Feels Good, or has Questionable Feel. Then, rank each purifier overall: Best Look and Feel, Second Best Look and Feel, Third Best Look and Feel, etc.

8) Years in Business: Generally, the longer a company has been in business the better. The number of years a company has been in business is part of its reputation. When comparing, rate each purifier: 11 years or more – Very Good, 6-10 years – Good, or 5 years or less – Newcomer. Rank each purifier Best Years in Business, Second Best Years in Business, Third Best Years in Business, etc.

9) Noise Level: How loud is the purifier? Most air purifiers make noise. On the quiet side, there are silent or near silent models. On the loud side, there are models that you would not want to sit near because they are so loud. Most models have multiple speeds/noise levels and can be adjusted or located in a suitable way. When you compare air purifiers, rate each: Quiet Noise Level, Average Noise Level, or Loud Noise Level. Rank each purifier Best Noise Level, Second Best Noise Level, Third Best Noise Level, etc.

10) Set-Up: How easy is the purifier to set-up? Many purifiers are plug-and-play. Some larger units are heavy and thus hard to remove from shipping boxes. Some have extra set-up or installation. A few require a licensed professional to install. When you compare air purifiers, rate each: Easy Set-Up, Average Set-Up, or Involved Set-Up. Then, rank each purifier Best Set-Up, Second Best Set-Up, Third Best Set-Up, etc.
