The SilverOnyx Air Purifier is not small. Although compact and lightweight, it can still be powerful enough to clean large rooms up to 500 square feet.

It has five levels of filtration that include UV-C and an Ion Generator to remove allergens and pollutants.

It can remove dust, pollen, and mold, as well as pet dander, smoke, odors, and

Germs and bacteria are also not spared. To ensure indoor air safety, the UV-C light disinfectant targets microbes in the air.

An air quality sensor is built into the air purifier to automatically adjust fan speed when in auto mode. In addition, the light indicator is useful to monitor indoor air quality.

The SilverOnyx is affordable for its features and performance. This is a great choice for those looking for an affordable large-room air purifier.

It looks almost like a coffee grinder in design. Although it’s not the most elegant of designs, it blends in with the space better than other boxy air purifiers.



Best Features

1. 5-Stage Filtration

Air Purifier Review

These are the five steps that air passes through when it enters an air purifier.

Mesh prefilter: This filter traps large particles such as dust and pet hair.

True HEPA filter: Traps smaller allergens such as mold, smoke, and pollen.

Activated Carbon Filter: Removes household odors from pets, cooking, and mustiness.

UV light sanitizer: Targets microbes in indoor air to make it safer

Negative ion generator: This releases negative ions to improve air purification and refresh the air.

SilverOnyx’s 5-stage filter makes it one of the most effective air purifiers for mold, smoke, dust, and other allergens.

It is also ideal for families who live in areas where wildfires are frequent.

2. Great for Large Rooms

The compact design of the air purifier belies its impressive coverage. It covers as much as 500 square feet.

The SilverOnyx is suitable for any job, including purifying a bedroom with a medium-sized bed or large basement.

3. Five Fan Speeds and Auto Mode

Air purifiers typically have three speeds. SilverOnyx has five fan speeds.

This allows you to choose the ideal setting for your room and the air quality.

To quickly clear the air of dust and other particles, turn the speed up to the maximum setting.

It is enough to endure the loud noise for a few moments.

Quieter level 3 is great for everyday use to maintain clean air.

You can choose auto mode if you’re not sure what fan speed setting is the best.

This mode uses the integrated air quality sensor (which measures the air quality).

It will increase its speed when the air is dirtier and slow down when it is cleaner.

4. Air Quality Indicator

The air purifier does not keep track of the air quality readings.

The air quality indicator can monitor indoor air quality. It is a light that changes color when there is poor air quality and turns blue when it is good.

5. Sleep Mode

To help you fall asleep, a handy sleep mode will dim the indicator lights and reduce the fan speed.

You can use the timer to have the purifier turn off after a specific time if you don’t wish to leave it on at night.


This air purifier has a significant problem that we’ve seen with other models: it can get noisy when it is running at the highest speed.

You don’t need to use the highest setting very often. It is only necessary for really dirty conditions.

Even then, it only lasts a few seconds.



The SilverOnyx air purifier will fit comfortably on a table or shelf and is an excellent choice for large rooms.

This unit provides powerful purification performance in a compact, lightweight design.
