GermGuardian AC5350B Elite Review: The Key Considerations 

Why an air purifier is vital

It doesn’t matter where you reside; whether it’s in a city or the countryside, several allergens, air pollutants, and bacteria fill our homes. 

As a result, a lot of people are seeing the need for an air purifier to enable them to breathe in clean air. An air purifier helps you breathe easily at night and also removes 99.97% of air pollutants from the atmosphere. 

If you have a health issue that worsens because of air quality, then an air purifier would be great for you. 

The function of an Ionizer?

An ionizer makes use of electricity to produce negatively charged ions into the air. When it does, dust particles that are positively charged ions stick to them and fall to the ground. This is because they’re no longer light. 

Small ionizers tend to release ozone in substantial amounts. You need to be careful to avoid polluting your air. 

Who should buy an air purifier?

To tell the truth, everyone needs to buy an air purifier. This is because it has so many benefits you cannot afford to miss. However, some people may benefit more such as elderly people, kids, those that have sleeping problems, people with hay fever and so much more. Breathing is very important as it is a natural thing. Therefore, we need to feed our lungs with quality air.

Other important details about air purifiers

You should know that an air purifier can eliminate 99.97% of air pollutants from the atmosphere. Imagine how great it would be to get rid of odors, dust particles, pet dander and every other pollutant in your new. It helps you sleep easily at night and wake up refreshed. All these would only be possible if you see an air purifier as an investment.

GermGuardian Elite 28 Review


  • Great air filtration process
  • It has a modern design
  • Comes with a 5-year warranty


  • Could be noisy when at its highest setting
  • Has a Low CADR rating

Guardian Technologies is truly a brand to reckon with when it comes to air purifiers. Also, their iconic air purifiers can be easily found in any air purifier store or supermarket. We will be doing the GermGuardian Elite 28 AC5350B Review next.

GermGuardian AC5350B Price

The GermGuardian AC5350B price is very much affordable. Interestingly, it is one of the best cheap air purifiers on Amazon. Just so you know, the Coway AP-1216L happens to be another superb choice when considering air purifier price. Across many online stores, you are likely to find the price under $200. 

Design And size

Because of color, you can easily mistake the GermGuardian AC5350B for the GermGuardian AC5300B. However, the GermGuardian AC5350B is not an ugly purifier just that the design lacks imagination. 

The front and backside have big air grills to display the great airflow system. It also has handles on both sides. The device has a circular light at the front to show when it is off or on. 

The GermGuardian AC5350B Elite 28 has a height of 28 inches and this makes it one of the tallest air purifiers. Well, this is something to differentiate it from the crowd. At the top of the device is a control panel, differentiating it from its predecessor. 

There’s also a digital display to show you the exact fan speed you’re on. With all these, the device weighs 11.25 lbs which makes it lightweight and easy to move about.

The Air Purifier Filter 

To know how powerful an air purifier is, you need to know how many filters it has and the types of filters they are. The GermGuardian  AC5350B elite 4-in-1 air purifier has a 4-in-1 cleaning system which we will break down below:

  1. Mechanical air pre-filter – This is made of a material that can be cleaned with a soft brush or vacuum cleaner. It helps to eliminate large air pollutants and particles from the air which may alternatively block the air purifier.
  2. Carbon filter – This is just the usual pre-filter all other air purifiers come with. However, this one has an Activated Carbon filter to help get rid of large particles as well as remove odors from cooking, smoke, cigarettes and so on.
  3. True HEPA filter – It has a true HEPA filter that captures 99.97 percent of allergens, molds, and dust as tiny as 0.3 microns.
  4. UV-C Light – This air purifier also has a UV bulb that kills bacteria, molds, and spores which are in the air. 

You won’t really find any explicit or distinct differentiating factor between the air purification system of the GermGuardian AC5350B and similar products released by Guardian Technologies. 

But you should also know that the True HEPA filter is the latest technology of the brand. Bear in mind that you need to change the air filters within 6 to 8 months for effective and efficient delivery.

Air Purifier Room Coverage 

The GermGuardian AC5350B covers up to 167 square feet of a room. It is the normal coverage for GermGuardian air purifiers. This is, however, a little smaller than others in the same price range as the Honeywell HFD300 which covers 225 square feet or even the SilverOnyx that covers up to 500 square feet.

The GermGuardian AC5350B’s ACH is 4X and this makes it able to clean and purify the air in your room every 15 minutes. The device’s CADR is 114 Dust/ 127 Pollen/ 108 Smoke (cfm).

The Sound 

The GermGuardian AC5350B has five fan speeds and this makes it a little bit noisy as it can go even up to 60 decibels. When at its lowest setting, the noise could get up to 40 decibels which is still high.

GermGuardian AC4100 Air Purifier 

The GermGuardian AC4100 could be the best air purifier for you. It can be placed on a tabletop which makes it quite portable. However, it has a bigger appearance than other portable devices from Guardian Technologies. 

In spite of the simple and sleek design, the device has a very strong system that works well in getting rid of all kinds of odor, fiber, pet dander, and other air pollutants. 

Another striking thing about this air purifier is its price tag. It has 3 fan speeds which come with different noise levels and rate of efficiency. This means that the low speed is quiet but it is not as efficient as the high fan speed. 

Then, the high speed is efficient but is noisy. The air purifier has a HEPA filter replacement indicator which helps you know when the HEPA filter needs a replacement. There’s also a UV-C light that can be on or off. If you want to buy a good air purifier on a budget, then this is the right one to go for.
