Air purifiers have become household staples for many, especially as concerns about indoor air quality continue to rise. But with popularity comes misinformation. From skeptical claims to outdated assumptions, there are plenty of myths floating around that can cloud your judgment when choosing the right purifier. Let’s clear the air, literally and figuratively, by busting five of the most common myths about air purifiers.
Myth #1: “Air purifiers don’t actually work.”
Air purifiers absolutely work. When used correctly and matched to the right space. Scientific studies have shown that PuroAir HEPA filters can filter up to 99.9% of airborne particles as small as 0.1 microns*, including dust, pollen, mold spores, and pet dander. The key is choosing a purifier with a high efficiency air filter and placing it in a room that matches its capacity.
Keep in mind that not every air filter is built the same. PuroAir HEPA air filters can filter particles down to an industry-leading 0.1 microns, compared to competitors that filter down to 0.3 microns. For example, 0.1 microns is 700x smaller than a human hair!
*Based on independent testing in an ISO 17025 certified lab on inanimate particles.
Myth #2: “They’re too noisy to use while sleeping.”
Modern air purifiers, such as the PuroAir 240, are designed to operate quietly, often below 22 dB, which is softer than a whisper or rustling leaves. In comparison, a standard refrigerator creates on average around 50 decibels of sound.
Features like sleep modes, adjustable fan speeds, and improved designs make them suitable for use in bedrooms. When selecting an air purifier, look for models that include dedicated sleep or night modes for optimal quietness.
Myth #3: “All air purifiers produce harmful ozone.”
Not all air purifiers emit ozone; only ionizers and ozone generators do. HEPA and active carbon filters, like those used in PuroAir purifiers, are ozone-free. When purchasing an air purifier, look for "ozone-free" or CARB-certified devices and avoid those labeled as "ionic" unless their ozone output is regulated. PuroAir purifiers ensure only clean, purified air is released into your space, free from harmful ozone.
Myth #4: “One purifier can clean my whole house.”
Air purifiers are designed for specific room sizes, and their effectiveness depends on factors like square footage, and floor plan (open vs. closed or traditional). PuroAir offers air purifiers for every room size - from small bedrooms or studio apartments to large open-spaced rooms up to 2,000 sq ft.
For larger homes, more than one floor, or multiple rooms, it's recommended to use multiple units. Consider whole-house air purification systems, such as the pre-built bundles offered, like the PuroAir Whole Home Bundle and Whole Home Plus Bundle.
Whole Home Bundle: includes 1x PuroAir 240 Air Purifier and 1x PuroAir 400 Air Purifier. This indoor air cleaning bundle is designed for spaces up to 3,000 sq ft*.
Whole Home+ Bundle: includes 2x PuroAir 240 Air Purifiers and 1x PuroAir 400 Air Purifier. This powerful pre-built air cleaning system provides over 4,000 sq ft* of whole home coverage.
For multi-level homes, please keep in mind that a single unit cannot purify the air across each floor level. For example, an air purifier on the second floor will not filter the air in the basement simultaneously.
Myth #5: “They eliminate all indoor air problems.”
While air purifiers like PuroAir's HEPA and Activated Carbon models can effectively reduce airborne gases from cooking, surface mold, and CO2, it is crucial to integrate them into a broader strategy that also includes source control and ventilation. Additionally, supplementing with products like the brand new PuroAir Mega MERV 13 HVAC Filter can further enhance air purification and odor control throughout a larger area.
