When it comes to pet allergies and air filtration, you may wonder what the advantage is to having both central air-mounted air filtration products and portable air cleaners. Customizing your air for allergy sufferers can be tricky for the simple reason that pet allergens can build up quickly in a small space like an apartment or condo bedroom. Allergy sufferers know that any exposure can trigger allergy symptoms, and doing double duty when controlling your air can prevent more severe allergy symptoms. The portable air cleaner can suck up the allergens nearest to the sufferer, while the "whole house" solution prevents allergens from spreading into other areas. Who wants to consider give up the cat or dog over allergy problems when double filtration can bring relief? Many allergy sufferers find this home air quality solution is very agreeable.
