Although these two products do share some similarities, each device is really made for different needs.

The 5-in-1 model is made for large areas of a home, office, or apartment while the 3-in-1 version is best for small rooms and personal spaces.

SilverOnyx 5-in-1 Air Purifier Review

The SilverOnyx 5-in-1 air purifier gets its name because it has a 5-stage air purification process.

With these five air filtering technologies combined, you get some of the cleanest, freshest air possible with an air purifier.

This product in particular also creates a sterile environment by destroying airborne germs with an Ultra Violet light—a feature you don’t find on many other air purifiers of this size.

As for the exact filter types, here’s how they work:

Filter Types

  • Pre-filter — When it comes to airborne pollutants, this filter is the first line of defense. It’s designed to capture large particles such as dirt, hair, dust, and others in a micromesh material.
  • H13 HEPA Filter — This is a superior HEPA filter and is the second-best you’ll find. The HEPA filtration captures 99.95% of harmful particles down to 0.3 microns in size. The next level up is H14 which is 99.995% effective (or 0.045%)
  • Activated Carbon Filter — The role of this filter is to reduce Volatile Organic Compounds (VOCs) and toxic fumes such as formaldehyde and acetaldehyde. These toxic substances are commonly found in indoor air and can have a negative impact on your health. This filter also reduces common household odors from cooking, pets, mold, and paints as explained in our guide on what does an activated carbon filter do.
  • Ultra Violet Light — This technology has been put into place to destroy bacteria, viruses, and mold spores. This leads to a more sterile environment that keeps you healthier and less prone to getting sick.
  • Ionizer (Anion Generator) — This technology boosts the air cleaning power of this machine. It works by emitting negatively charged ions into the air to make pollutants easier to capture in the HEPA filter. (It can be turned on or off.)

One of the best parts about the SilverOnyx 5-in-1 air purifiers is the internal filter set has a 360-degree design.

This cylindrical shape gives this machine 60% more surface area than air purifiers that have flat filters. That means it can remove more harmful pollutants and allergens from the air at a faster rate, making it a more efficient air purifier overall.

As for filter life, you can expect to change it every 6-12 months, depending on the quality of air inside your home, office, or apartment.

Room Size Coverage

As you just learned in the first section of our SilverOnyx air purifier review, this product has an incredibly powerful air filtration system.

Another standout feature is that it has the ability to cover 500 square feet (sq. ft.) of space.

To put the size of 500 sq. ft. into perspective, it’s more than enough to cover any common room found inside a home, office, or apartment.

This air purifier would be great for areas such as:

  • Open floor plans (where the living room, dining room, and kitchen are combined)
  • Large bedrooms
  • Basements, whether finished or unfinished
  • Workshops and/or garages
  • Office spaces that have room separations (not wide-open with rows of cubicles). See our best air purifier for office reviews to see how this unit compares.

SilverOnyx 3-in-1 Air Purifier Review

Photo of SilverOnyx 5-in-1 Air Purifier

Consider the SilverOnyx 3-in-1 air purifier to be the little brother of the 5-in-1 model.

It’s not quite as powerful as the 5-in-1 air purifier but it still contains the essential features for purifying the air in a small space.

Interestingly, SilverOnyx calls this model a “3-in-1 air purifier”; however, it’s technically a 4-in-1 air cleaner. We’re not sure why, but SilverOnyx chose not to count the “pre-filter” as an air purification stage like it did in the 5-in-1 model.

Because that’s how it was named, in this SilverOnyx air purifier review we’ll refer to this model as a 3-in-1 air purifier.

Filter Types

  • Pre-filter — Like the SilverOnyx 5-in-1 model, this filter is designed to capture large particles such as dirt, hair, and dust in a micromesh material.
  • H13 HEPA Filter — This 3-in-1 model also comes with a high-quality HEPA filter. It has incredible air filtration and removes 99.95% of particles down to 0.3 microns in size.
  • Activated Carbon Filter — Just like in the other model, this filter removes Volatile Organic Compounds (VOCs) and toxic fumes from the air.
  • Ionizer (Anion Generator) — It has an ionizer that can help boost the air cleaning power of this machine. (It can be turned on or off.)

As for filter life, you can get around 6 months out each one before they need to be replaced.
