GermGuardian AC4300 Review

The GermGuardian AC4300 PetPure air purifier is made by a brand that has a strong reputation for creating the most versatile air purifiers.

This air purifier, in particular, was developed with pet owners in mind.

Not only does it include powerful air cleaning features to keep pet dander, hair, and odors out of your indoor air, but it also helps protect the health of your animals too.

GermGuardian AC4300 Air Filter Types

GermGuardian AC4300 Filters

The GermGuardian AC4300 air purifier comes with a three-stage air filtration system that includes:

  • Activated Carbon Pre-filter – This special pre-filter is made with Activated Carbon which has the ability to remove pet odors. It also traps the largest contaminants like pet hair, dust, and dirt. Additionally, this filter can also reduce airborne gases and chemicals called “volatile organic compounds” or “VOCs” that are commonly found inside our homes.
  • True HEPA Filter with Pet Pure Treatment – Pet dander ranges in size, and most of it is microscopic. So, the True HEPA filter works to capture 99.97% of particles that are 0.3 microns in size, such as pet dander, dust, and other allergens. This filter also has a special Pet Pure antimicrobial treatment that inhibits the growth of mold and odor-causing bacteria on the filter’s surface.
  • UV-C Light – This feature protects you and your pets from harmful germs that could impact your health. The UV-C light is the only technology that can destroy airborne viruses, bacteria, and mold spores. It can be turned on or off.

The air filters last between 6 to 8 months before a replacement is needed.

The UV-C light can last up to 12 months or more depending on how often it’s used and the environmental factors.

The GermGuardian AC4300 PetPure air purifier is a slim unit but covers a decent amount of space.

The GermGuardian AC4300 can clean the air in rooms up to 153 square feet in size.

Here's how other GermGuardian air purifiers we've reviewed compare:

GermGuardian AC4300 ACH Rating

All air purifiers have an ACH rating.

The ACH rating is short for “Air Changes Per Hour” which informs you of how many times an air purifier can clean the air inside a room.

The GermGuardian AC4300 has a 4x ACH rating.

What this means is that this unit can clean the full volume of air once every 15 minutes or four times in one hour.

Having an ACH rating of 4x makes the GermGuardian AC4300 air purifier a very efficient device to own.

If you want to learn more about how this number is calculated, then check out our guide on how to calculate ACH; however GermGuardian already gives this data to you.

GermGuardian AC4300 CADR Rating

In addition to having an air purifier that does a good job of removing pet dander, hair, and odors, you also want it to remove other common pollutants that impact you and your pet’s health, including dust, pollen, and smoke.

The Association of Home Appliance Manufacturers (AHAM) puts air purifiers to the test to see how well they work to remove these elements, and the results are called the “CADR rating” or “Clean Air Delivery Rate”.

When it comes to getting an effective and efficient air purifier, the CADR numbers need to be at least 2/3 of the room size coverage.

The CADR ratings for the GermGuardian AC4300 air purifier are:

  • Dust: 107
  • Pollen: 116
  • Smoke: 99

These measurements meet or exceed the 2/3 rule that’s outlined by the AHAM.

Top Features

The GermGuardian AC4300 air purifier is a simple device that comes with some good features to make it easy to use.

GermGuardian AC4300 Air Purifier Controls

Those top features include:

  • 3 Fan Speeds – With multiple fan speed settings, you can choose how fast or slow the air purifier cleans the air. The low fan speed setting is ultra-quiet so you can use the air purifier in a bedroom without any worries. The highest fan speed is good for times where extreme odors, dander, or hair are present and you want to quickly remove those contaminants. The medium speed is a good in-between setting for everyday use.
  • Filter Replacement Indicator – This feature lets you know exactly when the filter on this unit needs to be replaced. That way, you’ll always have a fresh filter that’s ready to capture the most airborne particles.
  • Carrying Handle – This handy feature lets you move the air purifier from room to room if you’d like. Having a handle means you don’t necessarily have to buy a separate air purifier for each room unless you want that convenience.
  • Energy Star Certified – This label ensures that the GermGuardian AC4300 uses the lowest energy possible to deliver clean, fresh air inside your home.

Who is the GermGuardian AC4300 Air Purifier for?

We’ve covered a lot of important information so far in this GermGuardian AC4300 review.

But, who would benefit the most from this device?

The GermGuardian AC4300 PetPure air purifier can be used by anyone, but it’s especially beneficial in homes with pets.

This air purifier was designed to tackle pet dander, hair, and odors and has a special Pet Pure antimicrobial treatment to prevent the growth of  od0r-causing bacteria and mold on the True HEPA filter.

Since it’s also good at removing pollen and other pollutants, this unit can also be used in homes where people suffer from allergies or asthma.

Being equipped with a UV-C light that can destroy viruses and bacteria, this air purifier is a great option for homes where people are trying to reduce the chances of their pets and themselves getting sick.

Overall, the GermGuardian AC4300 air purifier is a good choice for anyone who wants clean air indoors.

The only airborne pollutants we wouldn’t recommend it for are for heavy tobacco smoke.

The CADR rating for smoke was on the low end, so it’s not the best choice for smokers. And, it wasn’t designed to be either.

Warranty Information

This air purifier comes with a 3-year limited warranty.
