So if you’re one of these people, then you’ll surely be interested in this air purifier . The GermGuardian AC5350B is one of the latest air purifiers from the company named Guardian Technologies and which I will tackle in this review its interesting features as well as its pros and cons, so stay with me!

germguardian-ac5300b-5350b-review Description of the AC5350B

The full name of this device is GermGuardian AC5350B 4-in-1 True HEPA Elite Air Purifier, very long doesn’t it ? Well this is because this unit has many technologies built-in it to help you breath a better quality air inside your home or office. The main job of this device is to get rid of household dust, plant pollen, mold spores and pet dander . So let’s go on these features one by one.

Activated Carbon Filter

From the time of the invention of the microscope, molds and bacteria are human enemies that scientists have always come with ways to get rid of and this filter is one of these. This Charcoal filter is able to stop the growth of these bacteria which could trigger dangerous health conditions. The Activated carbon filter performs also the task of reducing common odors from pets, smoking and cooking. This is a very interesting feature because no one likes to see his guests waiting for the next opportunity to rush out of the house due to repulsive smoking or pet odors.

UV-C Technology

Another threat which is unseen to the eyes, and which you’re probably exposed to, are airborne germs. Germguardian’s Ultra Violet light works along with Titanium dioxide to exterminate these airborne germs. In other words, when the air is sucked in, the light hits it and kills the bad germs then blows the good air out. The UV-C can be turned ON or OFF via UV-C Mode button. To keep this process of killing airborne germs effective, the light bulb inside this unit should be changed at least take six-eight months depending on the frequency of use.

True HEPA Filter

This is a feature which is found on many Germguardian air purifiers and which is capable, according to the company, of capturing 99.97% of dust and allergens as small as .3 microns such as household dust, pet dander, mold spores and plant pollen. According to the American Academy of Pediatric Allergy and Immunology doctors recommend this type of air filtration features to reduce exposure to indoor asthma triggers.

Digitalized UnitGermGuardian AC5350BCA – Air Purifier Review-Amazon

This air purifier a digital display panel to enable you to control the functioning of the unit in a way that matches your needs. The digital panel is easy to use and includes UV-C control, a filter change indicator and a timer. The fan speed has 5 levels to raise or lower the speed by which the air is cleaned. It was reported that only the first three levels are quiet, especially the first one which is ultra-quiet, ideal for sleeping. This wide range of speeds is very useful because when it’s daytime, the need for cleaning indoor air is generally more urgent (high fan speed), while at night, and to have a good sleep away from the buzzing sound of the fan, the lowest level is the adequate one.


In addition to innovative technologies, Guardian Technologies have produced one of the best looking air purifiers on the market. The unit’s look is very important, which will spoil your home decor if it’s not a nicely designed one. Unlike the futuristic look of the previews Germguardian AC4825 air purifier, this one is has minimalistic style with flat design and rounded corners. This gives the unit, along with the shiny black color, a really classy look. This GermGuardian Elite is 28 inch tall.

Germguardian AC5000E Review

Germguardian AC5000E Review

germguardian ac5000e

No doubt that you can always find on the market other air purifiers from different brands, but not all of them have the variety of functions that the Germguardian AC5000e can execute, and this is why in the advertisement of this product they focus on this sentence ” 3 in 1 Air Purifier True HEPA “, and actually this is true, the AC5000e goes through 3 stages of air filtering, and i will cover all these in this review, you will find also what this model offers you to make the air you breath pure and healthy !

So before getting technical let me summarise for you what the Germguardian AC5000E can achieve, we can list down its abilities in 4 major points :

germguardian ac5000e purifying steps

• It kills airborne germs and bacteria.
• It Captures airborne allergens, such as : household dust, pet dander, mold spores and plant pollens
• It Removes odors and smoke particles.
• It Kills airborne mold spores and other allergens.

Now let’s talk about the 3 stages of the 3 in 1 Air Purifier.
In the first stage, larger particles are trapped by the pre-filter system that uses activated carbon filter, i mean by larger particles : dust, hair, lint, it can also trap larger pollutants, and more importantly removes odors coming from household pets, tobacco smoke and cooking.
The second stage, is where the air filter called True HEPA ( High efficiency Purification of Air) comes to play, as it is able to  capture 99,9% of airborne allergens, technically a down to .3 microns in diameter, why this small ? well this what gives the Germguardian the ability to capture stuffs like dust mites, pet dander, plant pollen…etc.
In the last stage, which is the third one in this system, comes the filtration using UV-C light, which is a technology used to eliminate the growth and development of microbiological organisms such as fungi, bacteria or viruses, and no you don’t have to be afraid specialists say that it is a chemical-free way to sanitize your home environment.

The size of the room that the AC5000 can purifies

This model is 28 Inch tall, suitable for medium to large rooms, larger than what the Germguardian AC4825 Model can cover, which is more than 155 square feet, it is CADR Rated 125, CADR stands for “Clean Air Delivery Rate” which indicates the volume of filtered air delivered by an air purifier, that means it can deliver 125 Cubic Feet of clean air per minute.

How noisy is this Germguardian ?

Well this is one of the great plus that the AC5000 have to offer as an air purifier, as it is really quite when considering what it is doing ! but if you want it to be extremely quite you must keep it on ” Low ” speed, so the fan can run quietly, and you can sleep peacefully with a clean air. You will rarely need to set the fan on the high level where the noise can be noticed but even on high it is not that loud.

This thing looks really nice !

An Elegant Air Purifier

I have to say that I really love the design, modern and serious. Until now, I didn’t come across an air purifier that is of the level of the Germguardian’s design. Of course it has to execute what it’s made for, but in my opinion, design is also important because you don’t want a unit that will spoil your interior design. In addition to that, the AC4825 has a very useful new feature that many other air purifiers don’t have, it’s the Indicator Lights for Filter and UV-C Bulb Replacement, so that you don’t have to remember the last time you replaced your filter to keep the purifier running at optimal levels.

Talking about comfort, the Germguardian AC4825 is very Quiet when on low level speed fan, a bit noisy when on high level. If there is one thing that is missing it is a remote control.

Cleaning the Filter

The AC4825’s maintenance is an easy task. In order to keep the vents dust free, take a soft dry cloth and wipe the unit down. In addition to that, you can vacuum the filters once every two weeks to keep the unit running smoothly. The filters replacement depends on how much you use the air purifier, but generally, it must be replaced every six to eight months. How do you know when you need to replace them? Well when the filter turns from white to gray or black, then it’s replacement time. It’s a good idea to buy an extra filter with the unit so that you have the filter at the right time.

Consider These Benefits

What’s more, Germguardian AC4825 is a Best Seller on Amazon with nearly 5 Stars ! It really offers a great value, especially when you consider it’s affordable price, compared with the competition.
