Cat dander is one of the major triggers of Asthma. If you've got Asthma you know exactly what I mean - you're fine when you're out of the house, but the moment you get home you can feel the symptoms starting. Here are four tips to help make living with a cat easier when you have Asthma.
You probably spend eight hours or more each day in your bedroom. This is the best place to use an air cleaner to reduce the airborne cat dander that you are currently breathing.
Your home's HVAC system just doesn't move enough air to sufficiently reduce airborne cat dander. A good quality HVAC system will filter the air about 7.5 times per hour with a standard filter, less with a Hepa filter. To reduce the presence of airborne cat dander, you need to filter all of the air in your bedroom 20 to 40 times per hour.
These types of products don't move enough air either. And, the airflow pattern is usually obstructed by a bed, chairs, and other objects which means the air often circles back on the unit itself and only part of the air in the room is actually filtered. The Association of Home Appliance Manufacturers (AHAM) rates portable air purifiers using a system called the Clean Air Delivery Rate (CADR). A really high-end portable unit might have a CADR rating of 250. Even the test used to determine the CADR rating only reaches a maximum of 450. To put that in perspective, to filter the air 40 times per hour at a particulate efficiency of 99.97% in a 15 x 15 foot bedroom, requires a CADR of 1,200. Portable air cleaners just can't do the job.
These types of air cleaners are often mounted on a ceiling fan motor. If you already have a ceiling fan you can save some money by removing the blades and mounting the purifier in the same holes. These solutions have an airflow pattern that reaches the whole room. They silently filter the air 40 or more times per hour, effectively reducing airborne cat dander.
