Circling around the controls, you have a standard power button and a change filter button that alerts you to change the filter via the residual life of filters display.

The light button will turn off all indicator lights to reduce light glare at night. Auto mode will automatically set the fan speed to high when a high level of dirty pollutants is detected and revert back to low when the surrounding air is clean. Sleep mode button that locks the fan speed to lowest for anonymous night operation. Vita-ions with activate/ deactivate the anion generator function. Like-wise the same for the UV button. The Airflow button will cycle between the 5 fan speeds.

Into the build quality, SilverOnyx True HEPA is well-fitted with zero off-gassings. The design is clean and elegant, but there are nicer air purifiers out there.

Filters And Performance

Despite its small dimension, SilverOnyx True HEPA UV air purifier manages to WOW us by fitting Advanced 5 stages air cleaning purification. When air is drawn into its filtration, the initial mesh pre-filter will trap dust, debris, lint, pet hair from proceeding, and protect the HEPA filter. The shielded True HEPA H13 filter will capture 99.97% of ultra-fine allergens as small as 0.3 microns including dust mites, pet dander, mold, pollen, and mildew. The active carbon filter neutralizes household smoke and odors from cooking, pet, cigarette, VOCs, asbestos, radon. For germs, bacteria, and viruses, you have the UV-C Light that deactivates the DNA of pathogens thus destroying their ability to multiply or spread diseases. The Vita-ion is basically an ionizer that diffuses negative ions to merge and pull down airborne contaminants for the filter to capture. Overall the filter quality is great and you have the option to disable both UV-light photocatalyst and vita-ion function when not in use.

Noise And Energy Usage

With the new brushless DC motor, SilverOnyx True HEPA noise level is very quiet that it is suitable as a bedside UV sanitizer. You will only hear white noise at the fourth to fifth speed and even that is on an acceptable level. For power output, SilverOnyx True HEPA is very energy efficient that you can run it 24 hours a day without adding a burden to your utility bill. The availability of Auto mode and sleep mode can greatly reduce the power consumption where the air purifier will only use higher speed when the room air quality is bad.

Ignore the 299 MRSP, you can get SilverOnyx True HEPA Air Purifier for just under 150 after discount. It comes bundled with a 5-stage air filtration that itself is worth every dime you paid. Unlike most of its competition, SilverOnyx comes standard with autonomous mode and a built-in air quality sensor. A premium feature that is not even available in some of the top-tier models.

As for the upkeeping, the filter cartridge can be expensive to replace depending on your room air quality. You will need to replace the combination filter cartridge every 6 months for optimal filtration. The UV-light bulb will also need to be replaced when the performance has dipped drastically after certain hours of usage.

There are 2 places to buy SilverOnyx True HEPA Air Purifier. The best place is of course Amazon where it comes with great discounts, bundled deals, free shipping, and 30 days return policy in case if you have a change of thought. Next is SilverOnyx's official website, where you enjoy almost the same perks except and competitive prices and hassle-free shopping. You can also go through the dealers or giant retailers like Walmart, Costco but the availability is not favorable.

HoMedics AP-T30 TotalClean 5 in 1

Same price region but with a compact body, and addons like a night light, and essential oil slot. Other than that it is incomparable with SilverOnyx.

InvisiClean Aura II 4 in 1

Around the same price (after discount) with the same set of filtration lineup. Lacks auto mode but gains a better output at the cost of a bulkier body.
