Design, size, placementGerm Guardian AC4825 Air Purifier

The design is a subjective matter, but I like this unit. It is slim and sleek, the Germ Guardian AC4825 air purifier very well fits in a corner. Just remember to leave space (at least 1 foot) between the wall and air purifier because air inlet is at the back of the unit. Also, don’t place anything in front of it because of the air outlet.

In my opinion, Germ Guardian AC4825 is pretty high – 21.5 in (54.6cm), higher than a normal bed. But tight width and depth compensate that.

An air purifier is a very light weight, only 8.82 lbs (4kg). So you can easily move it from space to space. Carrying handle makes it easier.

 How it works and what sources of indoor pollution destroy

Germ Guardian AC4825 Air PurifierThis air purifier works with a fan – dirty air is sucking through filters.

Does it work and destroys everything that is mentioned in the picture above? Yes, it does.

I have a very sensitive nose and usually, smell odors that others don’t. Germ guardian AC4825 removes cigarette and kitchen odors pretty fast. It also doesn’t have problems to remove dust mites, mold spores, pollen. It helps if you have respiratory issues, dust mite allergy etc.

Features

  • The control panel is easily accessible, it is on the top of air purifier.
  • The control panel is very simple – UV-C bulb button and power knob which switches air purifier on low, medium and high mode.
  • Carrying handle helps you easily move it from space to space
  • Energy star certified – 40% more efficient than standard models

Noise level

The manufacturer says quiet operation. But it is quiet only on low setting. Of course, during the day highest fan speed will not disturb you but at night you should use first speed.

CADR

CADR – clean air delivery rate.

  • Dust Rating: 131 CADR
  •  Smoke Rating: 112 CAD
  •  Pollen Rating: 123 CADR

For you to better understand CADR lets calculate.

Germ Guardian AC4825 is recommended for rooms up to 155 square feet.

Let’s say regular ceiling height is 8 feet. 155×8=1240 cubic feet.

Next, just calculate how much time it takes to cover all room.

  • To remove dust: 1240/131 = 9.5 minutes
  • To remove smoke: 1240/112= 11 minutes
  • To remove pollen: 1240/123= 10 minutes

Now it is much easier to understand how effective will be an air purifier.

Maintenance and upkeep

You will have to change filters every 6 to 9 months. That’s individual. There is no filter change indicator so you will have to look at the filter. If the filter is white, it is ok. If the filter is dark gray or black, you should replace it. To elongate filters life, you can clean lint and dirt from filters regularly. Pre-filter and HEPA filter comes together and costs approximately $30. So that would be $60 in a year.

Filters change is simply. Remove the back filter cover, pop out the used filter, and install a fresh one.

The UV-C Bulb should be replaced every 10 – 12 months depending on use. It costs around $30.

On the high setting, Germ Guardian AC4825 consume 55W plus 5W bulb. Together 60W wattage. That is less than your PC or TV. A little bit more than a fridge.

Summary

I am not surprised that this Germ Guardian AC4825 is the best seller. It costs under $100, delivers clean air in 10 minutes (if use in recommended size room), saves space, light weight, easy control panel. Ideal for allergy and asthma sufferers.

My name is Ryan. I have had a hard time dealing with my allergies. Happily, I found that an air purifier was effective to ease my allergy symptoms. I spent a lot of time researching the best air purifier. I know how hard it can be to find the suitable one.

During the reading period, I also read a lot about humidifiers and dehumidifiers. I learned the mechanisms behind the technologies as well as the manufacturers and organizations within the industry.

I now feel convinced that I have built a guide that shows you all you need to know about air purifiers, humidifiers, and dehumidifiers. So I came up with the idea of creating this website.
