Comparison Insights: The Top 3 Contenders
When looking at the Clorox XL HEPA, the TruSens Z-7000, and the Skye 5-Stage, the differences come down to scale and technology.
The Clorox XL is the budget king of large spaces. It lacks the UV-C “kill” stage found in the other two, but it moves air more cost-effectively. Its filter replacements are standard HEPA, making them easier on the wallet over a three-year period.
The TruSens Z-7000 is the professional’s choice. Unlike the Skye, which focuses on smart sensors, the TruSens focuses on dual-sided filtration and commercial durability. It is significantly heavier and more robust, designed for environments where the air purifier runs at max speed 24/7.
The Skye 5-Stage offers the most sophisticated filtration sequence. It is the only one in the top three to include PRO-CELL technology for chemical gas removal. While the Clorox and TruSens are better for pure volume, the Skye is better for “difficult” air that includes both viruses and heavy chemical odors.
Final Verdict
Finding the best air purifier for covid requires balancing your room size with your willingness to maintain the device. After analyzing the airflow metrics and filtration ratings of all eight products, here is my final ranking:
- Best Overall: Clorox HEPA Air Purifiers (XL Room). It strikes the perfect balance between high-volume air cleaning, accurate particulate sensing, and a price point that doesn’t feel like a “luxury” tax. It is the most practical choice for most homes.
- Best Value: Clorox HEPA Air Purifiers (Medium Room). For under $100 in many markets, getting a true HEPA filter with a 360-degree intake and a real-time sensor is unbeatable. It provides the same core protection as the XL but for smaller zones.
- Best for Beginners: Philips GoPure GP5611. If you are new to air purification, starting with your car or your desk is a low-risk, high-reward move. It’s simple to use, requires no complex setup, and introduces you to the benefits of UV-C and HEPA tech instantly.
Buying Guide: How to Choose Without Overspending
1. Focus on HEPA Ratings, Not “Smart” Features
In my experience, many brands charge an extra $100 just for a Wi-Fi chip and an app. While these are convenient, they do not help the best air purifier for covid do its job.
* Look for “True HEPA” (captures 99.97% of 0.3 microns).
* Avoid “HEPA-type” or “HEPA-like,” which are marketing terms for lower-density filters.
* Prioritize a higher CADR (Clean Air Delivery Rate) over a fancy touch screen.
2. Calculate the “Filter Tax”
Before buying, check the price of replacement filters. A cheap air purifier can become expensive if:
* Filters need to be replaced every 2-3 months instead of 6-12.
* Proprietary filters cost 50% of the unit’s original price.
* The unit requires multiple different filters to be changed at different times.
Common Questions About best air purifier for covid
Can an air purifier actually capture the Covid-19 virus?
Yes, but with a caveat. While the virus itself is very small, it usually travels in larger respiratory droplets. A True HEPA filter is rated to capture particles as small as 0.3 microns with 99.97% efficiency, and it is actually even more efficient at capturing the tiny particles (0.1 microns) that viruses travel on due to a physics principle called Brownian motion.
What is the best air purifier for covid for a small apartment?
The Clorox Medium Room HEPA is likely your best bet. It provides five air changes per hour in a 225 sq. ft. space, which is critical for reducing viral load in smaller, poorly ventilated areas without taking up much space.
Is UV-C light necessary in an air purifier?
It is a valuable secondary layer. While a HEPA filter traps the virus, a UV-C light (like the one in the TruSens Z-7000 or Philips GoPure) helps “inactivate” or kill the pathogens while they are stuck in the filter, preventing them from potentially being released during a filter change.
How often should I run my air purifier for maximum safety?
I recommend running it 24/7 on a low or “Auto” setting. Viral particles can linger in the air for hours, so consistent filtration is much more effective than turning the unit on only when you are in the room.
Does a higher CADR always mean a better purifier?
Not necessarily. A higher CADR means it moves more air, but if the filter isn’t high-quality (True HEPA), it’s just moving dirty air faster. Look for a balance of a high CADR and a verified True HEPA or H13 rating.
