Ever wake up feeling stuffy or like it’s hard to breathe? Your room might be filled with dust, pet fur, smoke, and even pollen if you left your windows open. Those allergens can do a number on your respiratory system. Your best best is to set up an air purifier with a HEPA filter to help relieve allergy and asthma symptoms. HEPA, which stands for high-efficiency particulate air filtration, traps microscopic particles in the air to improve the air quality. Bonus: You may get a reimbursement on your electric bill or a rebate if you buy eco-friendly versions. Check with your town’s electricity provider to see if they offer rebates for high-efficiency products.
