Check to make sure nothing is blocking the air inlet. If there is nothing obstructing the inlet and there is decreased air flow, the HEPA or carbon filters may need to be changed. Check filter condition and replace if necessary.

Check to make sure the unit is plugged in and the electrical outlet (or circuit breaker) is working properly. Make sure the unit is turned on by pressing an operating speed button. If the door is ajar the unit will not operate. Make sure the filters are properly installed and firmly close the door

Most of our models include a filter indicator to take the guesswork out of filter replacement. Please see the owner’s manual for specific operation of this feature.

Always turn the unit off and unplug before cleaning. Once unplugged, use a soft, damp cloth and a non-abrasive cleaner (optional) to wipe the grill area and outside of the unit clean. 

Remove all filters before storage, as carbon filters will continue to absorb odors though the unit is not in operation. Then store in a cool, dry location.

The room size is generally recommended based on unit’s performance ratings (CADR). Most air purifiers would have the appropriate room size reference on the front of the packaging.

Some Air Purifiers have an independently controlled ionizer, which, when turned on, releases negative ions into outgoing filtered air. Ions are tiny particles that carry a positive or negative charge. These ions exist naturally around us, in the air, water and ground. Both positive and negative ions are colorless, odorless and completely harmless. Negative ions help the air purification process by attaching themselves to very small airborne particles in the room. You may also note after extended use, that dust may have collected around the grills or front panel. This is from the ionization affect caused by the negative ions exiting from the air outlet. This is additional evidence of the air cleaning effectiveness of negative ions. The dust can be easily removed with a clean, damp cloth or soft brush. Finally, using your ionizer may result in an occasional popping or cracking sound. This is a normal sound, generally caused by particles of dust that are interrupting the flow of ions, causing a small build-up of ions that, when discharged, cause the popping or cracking sound. NOTE: It is important to replace the HEPA filter at the recommended intervals in order to maintain optional air quality.

Today’s energy efficient homes are built to hold air inside, avoiding heat loss in the winter and heat gain in the summer. Of course, what’s better for your energy bills isn’t necessarily better for indoor air quality. This type of tight construction doesn’t allow the home to breathe. Opening a window isn’t always the answer either. That’s when an Air Purifier can help, especially if someone in your home suffers from allergies.

• Tobacco smoke – is one of the smallest allergens, and for years the Environmental Protection Agency (EPA) has reported the link between second-hand smoke and negative health effects.
• Pollen – It comes from trees, flowers and grass, and even opening a door can allow millions of these particles into a home. Some people are particularly sensitive to the presences of certain pollen particles.
• Animal dander and saliva – People who are allergic to cats and dogs are actually allergic to the dander flakes their pets shed. Dander can remain in a home long after the presence of the host animal. Also, the protein found in animal saliva is the most allergenic part of an animal. Both animal dander and saliva can be found in carpeting, bedding and on the furniture – basically anywhere your pet has been.
• Mold and mildew – Typically found in the shower, kitchen or basement, these sneaky plant spores also grow any place that’s warm and humid.
• Dust – A combination of bacteria, atmospheric debris (mainly invisible) and other airborne particles (visible to the naked eye). Although not always detectable by the eye or nose, many of these air pollutants create a hazardous environment, which negatively affects the air you breathe and can aggravate and instigate allergy symptoms.

Most air purifiers are tested for efficiency in terms of Clean Air Delivery Rate (CADR). These ratings indicate the volume of filtered air delivered by an air purifier, allowing you to compare one air purifier to another. The higher the CADR number, the faster the unit filters the air.

An air purifier cleanses the air in your home by removing allergens and pollutants from the air including dust, dander, odors, smoke, germs, etc. Air purifiers are the best way to clean indoor air & help to maintain a healthy indoor environment.

A micron is approximately 1/300th the diameter of a human hair.

Replace filter every 8-12 months

The carbon filter layer is used to trap large airborne particles & to help reduce odors, such as smoking or cooking.

True HEPA filters are designed to capture up to 99.97% of airborne particles as small as 0.3 microns. HEPA stands for “High-Efficiency Particulate Air”, which means its high effective at trapping particles in the air.

The limited warranty covers defects in materials and workmanship for all parts of the product, excluding filters & accessories. Damage from misuse, improper installation, alteration of the product or accidental breakage are not covered. Check your specific warranty for complete coverage information. If you are still unsure if your product is covered, please contact Consumer Service for further verification before returning your product.

Only models that are defective in material and workmanship are covered under the Warranty provisions. We do not provide routine inspection and cleaning services. Please refer to your user manual for specific instructions on how to perform these tasks.

At our discretion, the Bionaire® brand team will replace any product under warranty with the same model or one of equal or greater value if your specific model is no longer available.

Expect to receive a replacement approximately 2-3 weeks after our Customer Service team receives the unit under warranty.

Proof of purchase is required to determine if a product is under warranty. For special circumstances, please contact our Customer Service team.

Either an itemized sales receipt showing the specific model purchased or an invoice for the product is the only acceptable proof of purchase. Credit card statements, cancelled checks, or handwritten receipts are not acceptable forms of proof for warranty purposes.

Check your owner’s Manual for the model’s specific warranty time period. If your proof of purchase is less than the warranty length, your product is still under warranty. If you no longer have your owner’s manual, you can find it online under Instruction Manuals
