    Frequently Asked Questions

    Get answers to common questions about our indoor air quality.

    What causes poor indoor air quality?

    Common culprits include dust, pet dander, pollen, mold spores, cleaning chemicals, cooking fumes, and outdoor pollution that infiltrates your home. Proper ventilation and filtration address all of these.

    What's the difference between air purifiers and air filters?

    Filters physically trap particles as air passes through. Purifiers actively neutralize pollutants using technologies like UV light, ionization, or photocatalytic oxidation. The best systems combine both.

    Do I need a whole-home humidifier or dehumidifier?

    Texas humidity varies seasonally. Many homes benefit from a humidifier in winter (when heating dries the air) and dehumidification in summer. We can assess your specific needs.

    How often should I change my air filter?

    Standard 1-inch filters should be changed every 1-3 months. Higher-quality 4-inch filters last 6-12 months. We'll recommend the best filter type and replacement schedule for your system.
