Dander and pollen attached to a dog's fur are major triggers of Asthma.If you've got Asthma and a dog you know exactly what I mean - you're fine one minute, but the moment you're around the dog you can feel the symptoms starting. Here are four tips to help make living with a dog easier when you have Asthma.
Even if the dog is restricted from your bedroom, pollen and dander are on your clothes and floating throughout the air of your home.Since 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 Asthma triggers that you are currently breathing.
Your home's HVAC system just doesn't move enough air to sufficiently reduce airborne dog 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 Asthma triggers, 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 dog dander.
