Friedrich C90B Air Cleaner Frequently Asked Questions


What will it cost to operate my Friedrich C90B Air Cleaner?

Because all Friedrich C90B Air Cleaners are ENERGYSTAR certified, the cost to your electric bill will be minimal. The Friedrich C90B Air Cleaner requires about as much electricity as a household light bulb.

What does ENERGYSTAR certified mean?

The ENERGYSTAR Program was created by the US Department of Energy (DOE) and the US Environment Protection Agency (EPA) to help consumers identify and purchase homes, buildings, and products that not only save money, but also protect the environment. A product that has been ENERGYSTAR certified ensures that the product meets the DOE and EPA’s strict guidelines for energy efficiency and superior energy performance. Energy efficient products save you money on your energy bill and decrease greenhouse gas emissions. By buying ENERGYSTAR products, you not only save yourself money, but also help save the environment.

How many filters does the Friedrich C90B Air Cleaner use?

The energy-efficient Friedrich C90B Air Cleaner uses a washable pre-filter, an Activated Carbon filter, and re-usable collector plates instead of HEPA filters. The plates trap particles like dust, dander, and pollen, while the Activated Carbon filters absorb odors and fumes and can be easily replaced. Instead of multiple filters that need frequent changes, the Friedrich C90B Air Cleaner only uses one carbon filter and a series of Collector plates that can be washed and reused whenever needed.

How often do I have to change the Friedrich C90B Carbon filter?

The life of your Carbon Filter will depend on your Friedrich C90B air cleaner usage. The concentration of odors and fumes in the air passing through the air cleaner will determine how long the carbon filter can be utilized. If your Friedrich C90B air cleaner filters high concentrations of odors and fumes, its filter life will be much shorter and will need to be changed to ensure effective use of the unit. Under normal conditions, with a medium concentration of odors and fumes, the carbon filter will last between three and six months.

How do I change the Carbon filter in the Friedrich C90B?

It’s simple! Remove the plastic cover from the activated carbon filter. Position the pre-filter closest to the electronic cell, near the rear of the unit, and insert the carbon filter to the front of the unit. Make sure the electronic cell is positioned with the airflow arrow on the end plate pointing toward the fan. Once properly in place, return the cover and you are done.

What’s the difference between the Friedrich C90B Air Cleaner and the Friedrich C90A Air Cleaner?

Although the basic construction of the Friedrich C90B Air Cleaner is the same as the Friedrich C90A Air Cleaner, the C90B air cleaner is the newest addition to this top-rated line of electronic air purifiers. Essentially, it is the Clean Air Delivery Rate (CADR) that has been improved in the C90B unit. The Friedrich C90B Air Cleaner delivers more clean air per square foot.

While the Friedrich C90A delivers maximum efficiency for a space of 465 square feet, the Friedrich C90B delivers clean air at a maximum efficiency for a space of 506 square feet. Additionally, the Friedrich C90B outperforms the C90A in capturing pollen, tobacco smoke, and dust. The difference between the Friedrich C90A and C90B is clear. Friedrich has not only improved on the efficient design, but they have also yielded better performance rates with the newer Friedrich C90B.

Do the Friedrich C-90B Air Cleaners come with Filter Replacement Light Indicators?

No, the Friedrich C90B Air Cleaners do not come with Filter Replacement Light Indicators. However, simply sign up for the Clean Air Club, achoo! ALLLERGY's Free Filter Replacement Reminder Program, and you'll never have to worry about when to change your filters. We will email you when its time to change your filters.

Where can I use my Friedrich C90B Air Cleaner?

The Friedrich C90B Air Cleaner works great anywhere. This air cleaner is recommended for bedrooms, offices, nurseries, and common areas of the home. If you are an allergy or asthma sufferer, the Friedrich C90B is the ideal unit for you, and we recommend using it in the bedroom, as that is where you spend most of your time.

Does the Friedrich C90B Air Cleaner produce ozone?

Like a fax machine or copier, the Friedrich C90B does produce minimal amounts of ozone during operation. The maximum allowable indoor concentration recommended by the Food and Drug Administration (FDA) and American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) is .050 parts per minute (PPM). However, the Friedrich C90B’s highest ozone level measured was only .014 PPM.

What type of warranty is offered for the Friedrich C90B Air Cleaner?

The Friedrich C90B Carbon filter and air cleaner carries a one year warranty. This warranty guarantees the air cleaner to be free of defects in workmanship or materials, under normal use and service for a period of one year from the date of purchase by the original owner.

Can I wash my Friedrich C90B Collector plates in the dishwasher?

Absolutely! You can wash the Friedrich C90B collector plates either in the dishwasher or by hand with a little soap and water. Either way, it's easy to clean these reusable collector plates.

What particles does the Friedrich C90B Air Cleaner eliminate?

Friedrich C90B Air Cleaners eliminate pollen, dust mite allergen, mold spores, aerosols, tobacco smoke, odors and fumes, and animal dander. These air cleaners are the perfect companions for allergy and asthma sufferers everywhere!
