If you’ve been worried about rising outdoor air pollution levels, you may be shocked to learn that indoor air quality can actually be significantly worse. Offices across the globe have gradually adopted the practice of installing air purifying systems for good reason. Office spaces tend to have lower levels of air circulation, of course, and that’s detrimental to employee health.

In addition, however, air purifying systems have been shown to prolong the lifespan of computers and other electronic equipment, as well as eliminating important productivity drains — nobody who’s dealing with allergen-related itchy eyes or stuffed noses performs their best, after all.

In the office, where employees may spend 40+ hours a week with little control over their environment, installing air purifying systems has made sense for a long time. Do you truly need to invest in an air purifier for home use, where you can easily improve air circulation by simply opening windows?

If you want to breathe in clean air as you eat, sleep, socialize, and increasingly also work, even if you’re too tired to vacuum or don’t want to open the windows, the question isn’t that hard to answer. Air purifying systems can work in different ways — they may use HEPA filters, UV light, or activated carbon filters, for example, but as long as their clean-air delivery rate exceeds 300, they all serve the same basic purpose.

Air purification systems trap airborne particles like bacteria, respiratory viruses that spread through aerosols, mold spores, pet dander, smoke, dust, vapors released by cleaning products, and pollen, offering you cleaner, more breathable air. Even if nobody in your household suffers from chronic respiratory conditions like asthma, having an air purifying system in place will reduce your risk of falling ill, eliminate minor but irritating symptoms like headaches and nasal congestion, and ultimately make for a happier home life.

Air purifying systems might once have been the sole domain of office spaces, but today, they’re affordable enough to consider installing an air purifier in your home. Your health is worth the investment.
