Germ Guardian AC4825E Air Purifier

Best Overall Air Purifier For Pets And Pet Owners

Product Overview

  • Dimensions: 9” x 5.5” x 22”
  • Weight: 8.55 lbs
  • Coverage area: 167 sq. ft. (15sqm)
  • Clean air delivery rate (CADR): 118㎥ / hr
  • HEPA Filter replacement frequency: Once every 6 to 8 months
  • UV bulb replacement frequency: Once every 10 to 12 months
  • Warranty: 3 years

The Germ Guardian is an air purifier for a medium sized room of about 167 sq. ft. For its air purifying capabilities, it features a 4 in 1 filtration system that consists of a HEPA filter, activated carbon filter, ultraviolet light and Titanium dioxide filter

The HEPA filter acts to remove the fine particulate compounds in the air such as pet dander, dust and pollen while the activated carbon filter targets gaseous compounds like the pet odors. Lastly, the UV light and titanium dioxide is responsible for deactivating any viruses and bacteria that may get through the HEPA filter. Ahead of these is a pre-filter which helps to trap larger particles like hair and fur while extending the life of the HEPA filter. With such a comprehensive filtration system, homeowners will not need to worry about pet dander, pet fur and pet odor in their homes when this purifier is working.

Designed as a tower model, the Germ Guardian purifier is a space efficient model that will not take up valuable space in your house. It can be easily slotted into a corner of the room without causing any hindrance to human traffic. However, because it is a tower design, it may sometimes topple when our pets get a little too close due to the higher centre of gravity.

When it comes to customization, there are 3 fan speeds to choose from depending on your air quality and needs. For homeowners intending to use this during their sleep, they can opt for the low fan setting which is ultra quiet and would not hinder their rest. There is also a on/off button for the UV light bulb so users can choose to use the air purifier without the UV light for better energy savings.

With a warranty of 3 years, this air purifier also has one of the longer warranty on the market. This ensures that the user is protected longer against defects and malfunction while also highlights how confident the manufacturers are regarding their product. 

One complaint about this air purifier that some users have voiced out is that it emits a plastic burning smell for about 10 to 15 mins during the first few uses. However, the smell does go away after the first few uses and does not return.


  • Comprehensive filtration system with HEPA, activated carbon and UV light
  • Space efficient design
  • Quiet at low fan setting
  • UV light can be turned off if not using
  • 3 years warranty


  • Tower design may get toppled over by pets
  • Burning plastic smell during the first few uses

What the fans love: “The smell of the litter box was the primary reason I purchased this air purifier. After using this air cleaner regularly for about two years, I can confidently say that it effectively and completely removes the smell of the litter box, helps control the amount of hair that floats around the room, and generally does a very good job keeping dust from accumulating in the room.”

Best Air Purifier For Pets & Pet Owners Buyers’ Guide

What Is Pet Dander

Pet dander refers to tiny particles of skin that have been shed from animals with feathers or fur. Dogs produce dander, cats produce danders and birds produce dander. Evidently, as long as we have pets in the house, pet dander is inevitable. Some pet danders are large enough to be seen with the naked eye while some can only be seen under a microscope. Nonetheless, pet dander is a major problem if there is anyone in your home suffering from allergies.

Why You Need To Care About Pet Dander

The shed skin from pets contains a type of protein that can potentially cause allergic reactions. When these pet dander is inhaled into our body or stuck onto our body, it can trigger a reaction from our body’s immune system. Because pet dander is considered a foreign body, our immune system naturally recognizes it as an invader and it starts producing antibodies for the proteins in pet dander. The antibodies then goes on to stimulate the mast cells in our body and this is manifested as a series of allergic symptoms. 

Some of these signs and symptoms include

  • Coughing 
  • Wheezing
  • Runny nose
  • Watery and itchy eyes

If the exposure to pet dander is prolonged or if the individual is especially allergic, the symptoms may progress further to more serious conditions like bronchitis, sinusitis and asthma.

How To Get Rid Of Pet Dander

  • Brush your pet regularly outside the house to remove dead skin cells 
  • Vacuum with a HEPA filtered vacuum cleaner
  • Keep your pets out of the bedroom and out of the bed
  • Wear a mask when cleaning the cat box or dog house
  • Use a HEPA air purifier to clean the air in the house 

Do Air Purifier Help With Pet Hair

Yes. Technically you do not need an air purifier to get rid of pet hair because pet hair is so much bigger and can be cleaned with a broom and brush. However, most air purifiers will have a pre-filter that can pick up objects such as hair and fur from the room. This acts as a 1st layer of filtration while the HEPA filter picks up the microscopic particles such as pet dander. Therefore, for homes with pets, an air purifier is essential to keep the house free of pet hair and pet dander.

Do Air Purifier Help with Pet Odor

Mostly yes. Air purifiers that contain an activated carbon filter will be able to remove pet odors from the house. Activated carbon filter is an adsorbent type filter that can pick up gaseous compounds such as odors and tobacco smoke. It cannot remove particles so it mainly acts as an adjunct to the HEPA filter. Nonetheless, if your home is struggling with pet odors, then an air purifier will surely help as long as there is an activated carbon filter.

Considerations When Choosing Air Purifiers For Pets

Coverage Area

When choosing your air purifier, you need to find out the size of your room as accurately as possible to avoid disappointment. The easiest way to find out the size of your room is to measure the length and breadth of your room and then multiply them together.

Once you have an idea of the actual size of your room, you can look at the models of air purifier that you are interested in. Almost all manufacturers will list down the coverage area of their humidifiers in the product overview. These give you a good indication of what size room the air purifier is best for. 

When looking at these values provided by the manufacturers, I would probably round them down by about 20%. For example, the manufacturer may say that the air purifier can cover an area of 500 sq. ft. but I would take away 20% from that and estimate the coverage area to be about 400 sq. ft. This is because these values were probably measured in an ideal environment where there are no leaks or drafts in the room. In real life, we may have leaky windows, wall cracks, door gaps that may contribute to the reduced air quality.

Noise Level

For many of us who may be suffering from allergies due to pet dander and pet hair,  the allergies get worse at night when we are trying to go to bed. Hence, having the air purifier turned on while we sleep is crucial for us to get a good night rest. Since the air purifier will be working in our bedroom, having a quiet air purifier will ensure our sleep does not get interrupted by the air purifier. Generally speaking, a noise level below 40 dB is quite acceptable for most people and should not disturb the sleep.


For any electrical appliances, the length of warranty is always something to consider. Obviously the longer the warranty, the better it is for the consumer. A long warranty is also suggestive that the company is very confident of their product’s longevity and durability. Generally in the air purifier sector, a warranty period of 1 to 2 years is quite reasonable and anything beyond that is considered good.

Presence Of Activated Carbon Filter

As mentioned earlier, an activated carbon filter is essential to adsorb funky odors from your pets. Gaseous compounds like odors can only be removed using this special type of absorbent filter. A normal HEPA filter can remove particulate compounds but not odors. Therefore, if you are struggling with pet odors in your home, look for an air purifier with an activated carbon filter. Something for homeowners to take note is that these filters do require replacements as well. Therefore, homeowners will need to check with the manufacturers the replacement frequency and see if it suits your needs.


Air purifiers can come in a few different designs. The common models are compact, tower and wall mounted. Each design would have its pros and cons and suitability in different situations. For a house with pets, I would go with either a compact or wall mounted model as they can be kept out of reach of our curious furry friends. A tower design air purifier may be prone to toppling if our pets try to climb or lean on it. While they are usually pretty sturdy and can withstand a knock or two, we would still want to limit any damage to our air purifiers.

Winix 5500-2 Air Purifier

Best Air Purifier For Large Rooms

Product Overview

  • Dimensions: 15” x 8.2” x 23.6”
  • Weight: 15.4 lbs
  • Coverage area: 360 sq. ft. (33sqm)
  • Clean air delivery rate (CADR): 360㎥ / hr
  • HEPA Filter/Carbon filter replacement frequency: once every 12 months
  • Warranty: 1 year

The Winix 5500-2 air purifier is a unit designed for larger rooms that can go up to 360 sq.m in size. It comes armed with a 4 stage filtration system that includes a washable pre-filter, a washable activated carbon filter, a true HEPA filter and the latest PlasmaWave technology. The pre-filter will be the first line of defense against the larger airborne particles, while the pet dander, pet fur and pet odor will be managed by the HEPA and carbon filter. Lastly, the PlasmaWave filter acts to neutralize bacteria and viruses. For any pet owner, this purifier got you covered and you can be assured of fresh clean air at home.

In terms of customization, this air purifier comes with an AUTO mode that is designed for convenience and efficiency. When using the AUTO mode, this unit is able to adjust its fan speed automatically based on the real-time air quality. This is made possible by a smart air quality sensor that detects and displays the indoor air quality in real time. This is a very useful feature for users that like that just want the job done without too much overthinking

Besides the air quality sensor, there is also an odor sensor and a light sensor. During Auto mode, the odor sensor detects the amount of odor in the environment to adjust fan speeds. The light sensor detects the amount of ambient light within the environment to adjust the brightness of the LED indicators.

Another mode that deserve a mention is the Sleep mode that is activated automatically when the room is darkened. The sleep mode ensures a quiet and energy efficient operation through the night that doesn’t disturb the user. Once the light is turned on again, the purifier will return back to Auto mode. For homeowners big on convenience, you will also appreciate the remote control that allows easy and convenient adjustment from the comfort of your couch.

There are 2 limitation to this air purifier. Firstly, there is no way to override the auto sleep mode. Therefore, if your house is fitted with dim lighting, this purifier will just be functioning at the low setting as it is in “sleep mode”. Secondly, the filter replacement is one of the most costly ones on the market. Thankfully, the replacement frequency is only once a year but these do add up if you intend to use the air purifier for a long time.

In summary, this is an air purifier loaded with features which can be really useful if you know how to make use of them. It is a little on the pricier side but it justifies the price tag with its quality. 


  • Comprehensive filtration system
  • Auto mode for convenience
  • Sleep mode with dimmed lights and quiet fan
  • Remote control enabled
  • Real time air quality sensors


  • Unable to override the automatic sleep mode
  • Expensive filter replacement

What the fans love: “This machine is amazing! In about an hour all smoke odor was gone and so far when set on “auto” it has kept the air fresh. The fan on the low setting is so quiet you have to hold your hand over the exhaust to see if it is running, even on the “high” setting it is quiet enough for a normal conversation. It is not overly large and being only about 7-8″ deep it fits against a wall making it less noticeable. The front access panel is held in place with magnets so it opens very easily making cleaning or changing filters a breeze”
