Why Isn’t My Air Purifier Working At Peak Performance?

The right air purifier can do amazing things for your indoor air. A high quality air purifier with a combination of True HEPA and activated carbon filters can remove harmful gases, bad odors, and 99.5% of particles from the air inside your home. This is important because indoor air is generally 2 to 5 times more polluted than outdoor air and pollutants have been shown to cause a lot of different health issues.

But, even the most effective purifiers work best under the right conditions. Find out what you can do to make sure that your purifier is at peak performance.

Purchase the right size purifier for your room

No matter how sophisticated your air purifier is, it won’t be as effective if it’s not the right size. 

CADR indicates how much air is filtered in an hour for three particular pollutants (smoke, pollen, and dust) in Cubic Feet Per Minute (CFM). The higher the CADR number, the faster the air purifier filters the air.

Using a purifier with a CADR that’s too low for your room size will result in less effective air purification, while one with an excessively high CADR will be an unnecessary waste of money and energy.

 Doing some simple math can help you find just the right size unit for your room.

The CADR of your air purifier should be equal to at least two-thirds of the room’s area.

So, for example, a room that is 15 feet by 10 feet has an area of 150 square feet. ⅔ of 150 is 100, so an air purifier for that room should have a smoke CADR of at least 100.

Place the purifier in the right location

An air purifier will be most effective if it’s in the right location. There are several factors to consider when deciding where to place your air purifier. 

Place it close to the source: Using a purifier in the rooms with the dirtiest air, as close to the source of pollutants as possible is the best way to keep your indoor air clean.

Look for the spot with the best airflow: It’s generally a good rule to make sure that the air purifier has at least a foot of space on the front, back, and sides of it so it will clean the air in the entire room instead of just a small corner. 

Be aware of vertical airflow: An air purifier that is 3-5 feet off the ground will be able to capture both the horizontal and vertical air movement. To take advantage of vertical airflow, smaller units can be placed on a table or desk while larger units can sometimes be mounted on the wall.

Stay away from open doors and windows:  Placing the purifier near windows or doors that are open lets in a constant stream of outdoor air and pollutants which your purifier will clean, using energy that could be directed to your indoor air. 

Avoid other electronics:  It’s best to give around 5 feet of distance between the purifier and any other electronic devices so that they don’t interfere with your purifier’s technology.

Move it around. There’s no rule that says your purifier needs to remain in one place. In fact, short of having a purifier in every room, moving the purifier regularly may be the most effective way to keep all areas of your indoor air clean.

Keep things clean

The cleaner your home is, the less your purifier will have to work, the more effective it will be. Some simple ways to reduce dust and other pollutants are:

Banish shoes: About 60% of household dust comes from outside. It gets in through windows, doors, vents and, on the soles of your shoes. 

Wash bedding frequently:  Dead skin flakes, dander, and dust mites are constantly building up on your mattress, pillows, and linens. Reduce bedroom pollutants by vacuuming your mattress seasonally, and laundering your bedding regularly.

Keep floors clean: Carpets and rugs collect dust and other pollutants. Avoid them whenever possible. Clean all your floors thoroughly at least once a week.

Use the right tools: Vacuum cleaners are excellent at dusting curtains, mini-blinds, and baseboards. Use a lightly wet cloth to remove dust from hard surfaces.

Change filters regularly

If you notice a difference in your purifier’s performance, it may be time to check your filter. HEPA filters typically need to be changed every 6-12 months.

To take the guesswork out of purifier maintenance, some devices come with built in smart systems to let you know when it’s time to change your filters and how well your purifier is performing. 

Clean air is a vital component of good health. These tips will help ensure that your air purifier is working at peak performance to keep you and your family breathing easy.

How Tax is calculated

The amount of tax charged on your order depends on many factors including the following:


  • The identity of the seller
  • The type of item or service purchased
  • The time and location of fulfillment


The shipment or delivery address of your order
These factors can change between the time you place an order and when your shipment is complete. As a result, the tax calculated on your order may change. We display an “Estimated Tax” to be collected at Check Out when confirming an order. The amounts displayed as estimated tax may then be updated later when your order is finalized and completed.


The tax rate applied to your order will be the combined state and local rates of the address where your order is delivered to or fulfilled from. For example, if you live in a state that does not impose a sales tax, you may still see tax calculated on your order if shipped to another state. Moreover, the tax rates applied to your order may also be different for a variety of reasons, such as a shipment to a residential home versus a business address. Also, the total selling price of an item will generally include item-level shipping and handling charges, item level discounts, and gift wrapping charges. If applied at an order level, these charges, may be allocated to the individual items in an order.


If you are ordering from aeris and shipping to a country outside of the US, you may be charged the applicable country tax rate.
