Are you still confused about the GermGuardian AC4825 vs AC4300? Let us dig deeper and find out what each has to offer.

What are the main differences between the GermGuardian ac4825 and ac4300?

Maximum Air flow capacity

  • The air flow capacity is the rate at which an air purifier takes in air and cleans air from its surrounding. The GermGuardian ac4825 takes the win for having the highest air flow capacity of 130 Cubic feet of Air per minute. The GermGuardian ac4300 takes in 120 Cubic feet of Air per minute. Even though it is a small difference, the GermGuardian ac4825 still leads the way on this one, even when it is not as noticeable when both are tested under the same room conditions.

Room Coverage

  • Both the GermGuardian ac4825 and ac4300 can filter air within indoor spaces. However, the size of the room that each can cover is different. For the GermGuardian ac4825, the largest room square footage it can cover is 167 sq. ft, and it is most effective when it is at maximum power.
  • In contrast, the GermGuardian ac4300 can cover a somewhat lower room square footage i.e. 153 sq. ft. And just like the GermGuardian ac4825, the process is most effective when it is at maximum power.

Size, Height and Weight

  • Both the GermGuardian ac4825 and ac4300 when placed close to each other are of almost similar size. The GermGuardian ac4825 has a cylindrical design and the GermGuardian ac4300 a boxy design. Both are approximately 22 inches, with the GermGuardian ac4825 having a weight of 8.55 pounds, and its counterpart the GermGuardian ac4300 having 9.45 pounds.

Clean air delivery rate (CADR)

  • CADR is a measure of the fraction of particles that have been removed from the air. For the GermGuardian ac4825, the highest CADR is 125 (for pollens) and the highest CADR for the GermGuardian ac4300 is 116 (for pollens).
  • It is important to note that the higher the CADR, the faster the air purifier filters the air.

The Purchase Price

  • The question of cost between the GermGuardian ac4825 vs ac4300 is amusingly confusing. Even with almost all features similar, the GermGuardian ac4300 is more costly than the GermGuardian ac4825.Though fundamentally, they both have the same functions.

What are the main similarities between the GermGuardian ac4825 and ac4300?

Ultra-Violent Bulb

  • The GermGuardian ac4825 and ac4300 both feature an Ultra-Violent bulb inbuilt at the back of the air purifier; whose main aim is to produce UV Light for killing germs. Remember, while it filters out the germs, the ac4300 also kills them.
  • UV-C light helps kill airborne viruses which include influenza, staph and rhinovirus. It also uses Titanium Dioxide to reduce volatile organic compounds.

Tower design

  • Both the GermGuardian ac4825 and ac4300 have a large form factor and a tower shape. For the GermGuardian ac4825, the edges are curved, whereas for the GermGurdian ac4300, the edges are boxy. This tower gives the air purifier room to take in a lot of air, and also hold a larger space for the HEPA filter and Carbon filter. The tower also speaks a lot as to why they are designed for somewhat larger rooms.

The HEPA Filter

  • The GermGuardian ac4825 and ac4300 have an inbuilt HEPA filter, whose main aim is to purify the air by doing away with tiny and very small particles, which may not be visible to the eye.

The HEPA filter has a fine mesh through which air passes and any external pollen or dust mites are removed. It can remove up to 99% of air pollutants and airborne allergens measuring 0.3 microns in size.

Carbon Filter

  • Right behind the HEPA filter lies a carbon filter for both the GermGuardian ac4825 and ac4300. This specifically purifies air by removing chemical vapors like cigarette smoke, mold odors and gasses or other smells.

No wireless connectivity

  • The GermGuardian ac4825 and ac4300 are BOTH manually controlled. They do not have wireless connectivity, like some other high end air purifiers.

Multiple fan speeds

  • The GermGuardian ac4825 and ac4300 allow for switching between their various fan speeds. They both allow for 3 fan speeds.

Manual controls on the device

  • The GermGuardian ac4825 and ac4300 have buttons that can be found on the air purifier control panel. You can use these buttons to specify the settings you want for your device.

Noise output

  • Both the GermGuardian ac4825 and ac4300 have a similar noise output. For lower power modes, the ac4825 and ac4300 produce less noise since less power is being used.

Distinct features of the GermGuardian ac4825

A Carbon filter + pre-filter

This is a combination of both a Carbon filter and a pre-filter. The pre-filter is a layer which prevents any larger dust particles from reaching the Carbon filter. This function is almost similar with the HEPA filter. Each of these filters still has to be replaced after being used for a period of time.

Fan speeds

A user can adjust between 3 fan speeds. Low, medium and high. The increase in speed increases with noise and therefore as you switch between the fan speeds, be sure to find ways to tolerate the increased sound produced by the air purifier. It is important to note that the low settings offer the most serene and quietest experience. Therefore, for a quiet operation, you can enjoy gentle white noise. This is the perfect mode for night time or a restful sleep during the day.

Multiple Levels of Cleaning.

The GermGuardian ac4825 has many levels of cleaning. These include,

  1. HEPA Filter: It is said to capture 99% of dust and allergens
  2. Charcoal + PCO Filter: Captures and dissolves airborne bacteria and mold
  3. UV-C Light: Works together with filters to kill germs and bacteria
  4. TIO2 treatment: Combines with the UV-C light to reduce VOCs

Pros Of the AC4825

  • Genuine parts for replacement: There are a number of distributors online who offer authentic spare parts for maintenance, starting with guardian technologies, their parent company who offers all kinds of replacements if needed.
  • Pocket friendly price: The GermGuardian’s initial purchase price is really affordable for almost any middle-income earner. In case you want to get the bare minimum of an air purifier at a low cost, this GermGuardian is the way to go.
  • Good air filter capacity: For an air purifier of its type, the GermGuardian ac4825 has a large air flow capacity of up to 130 Cubic Feet of air per minute.
  • HEPA + Carbon filter: Considering its price range, and having both filters which are desirable for the ultimate air safety experience (HEPA filter for fine particles and Carbon filter for smells), it is one to die for.

Cons of the AC4825

  • Filter Clogging: All the larger particles that get stuck in the pre-filter are not removable and clog it up over time, so you must replace it since it is not washable.
  • Poor Carbon filter quality: There is less carbon and thus it doesn’t do much of an effective job dealing with odors and gasses. With further analysis, you will realize that the carbon filter is not dense enough, as compared to others.
  • Poorly implemented UV Light:  A large area through which air travels is not well exposed to UV Light. The mode of operation is that the UV Light is supposed to kill germs found in the air. The UV light in this case is not able to treat all the air because a large portion of the air flowing through the purifier is not exposed to the light.
  • Does not have wireless capability
  • It also does not have air quality reporting
  • No auto mode functionality: All changes and controls are supposed to be made manually by turning the knob.
  • Maintenance expenses: There is a constant need to change the air filter, and the continued maintenance can mean to be costly. The price of an air filter for continued replacement can put a toll on the buyer’s budget, and users are advised to change air filters per year.

Unique features of the GermGuardian ac4300

Better cleaning technology

To give it a better cleaning edge, a fibrous material covering the HEPA filter was placed on one side. This helps to keep out larger particles.

Electronic control panel

In order to easily see and adjust your control setting, the GermGuardian has an electronic panel on the air purifier. The panel has convenient indicators that let you know when to change the filters

As you can see, there are not a lot of special features with the GermGuardian ac4300. This is because it is almost similar to its counterpart the GermGuardian ac4825.

Pros Of the AC4300

  • Recommended for Allergy and Asthma sufferers
  • AHAM Verified and Energy Star Certified

Cons Of the AC4300

  • Low quality gas filtration
  • Poor location of the UV light: The UV Light is located in a different compartment and is prevented from casting its rays to the largest part through which air flows. Its effectiveness becomes questionable because of this.
  • Room coverage: It is not effective in purifying the air in rooms larger than 160 sq. ft.
  • No wireless capability
  • Price: The GermGuardian ac4300 costs more than the GermGuardian ac4825 even when it is not that different from the GermGuardian ac4825. This surely gives it a less of an edge over the ac4825, since it does not have that many feature advancements added to it.
  • No air quality reporting.
  • It doesn't have auto mode functionality: All changes and controls are supposed to be made manually by turning the knob.
  • Costly Maintenance: There is a constant need to change the air filters, just like its counterpart the GermGuardian ac4825. A single filter will need to be replaced occasionally every 6-8 months depending on how the product is used.
