Indoor Air Filtration for HVAC Units.

Most of us spend the majority of our time inside homes, offices, or other enclosed spaces these days, and that means the quality of the air we breathe indoors is now a critical factor in overall health. And for no one is this more true than those who suffer from allergies and respiratory issues. The good news is that improving your indoor air quality here in San Antonio is possible, and it’s effective for those with respiratory concerns.

Can Improving My San Antonio Indoor Air Quality Help With Allergies and Respiratory Issues?

Some of the common pollutants that lurk in our indoor air include volatile organic compounds (VOCs) released from household products like paints and furniture; biological contaminants like mold spores; and allergens, which come from dust, pests, pets. Even everyday activities that we have to engage in, like cooking, can introduce fine particles and gases into the air that irritate the lungs.

These pollutants can trigger immune responses in sensitive individuals, and poor indoor air quality has been linked to a range of health problems, from mild breathing difficulties all the way up to increased hospital visits. When your indoor air is laden with irritants, your body’s immune system goes into overdrive producing histamines. The lungs and airways are the first line of defense against inhaled pollutants, so chronic exposure can lead to inflammation, reduced lung function, and a higher susceptibility to infections like the flu or pneumonia. Here’s how to deal with it:

Get Better Ventilation

One of the best things you can do is just get better ventilation: open windows when outdoor air is clean or use exhaust fans in kitchens and bathrooms. This fresh air exchange will dilute the indoor contaminants.

However, if you live in a high-pollution area (like right up against a major road), you’re in a building where windows can’t open (like an office), or it’s too hot or cold to open up (a lot of the year here!), mechanical ventilation systems with filters can achieve similar results. An HVAC system with high-efficiency particulate air filters (HEPA filters) will capture tiny particles like allergens and dust and improve life for everyone in the building.

Keep Things Cleaned and Serviced

Your HVAC system can do a lot, but not if it’s full of dust. Regular cleanings are going to make a huge difference, but they have to be done right, without stirring up dust or driving it deeper into the system. At Beluga Air, we’ll come do a careful assessment of your system, then use our advanced equipment to do a real deep clean. We don’t shove dirt and dust deeper in: we remove it entirely. Then we’ll sanitize your system to ensure no mold, bacteria, or their spores remain.
