An air purifier is a must have especially for people who tend to experience asthma attacks, or even those who are just generally very sensitive to dirty air. It\u2019s something that you can get if you\u2019re not quite comfortable with the air quality in your house, and is also something that\u2019s key to have if you have a lot of pets in your living space and would want to get rid of their odour. Picking the best air purifier for you involves having a good idea of how large your space is, as well as the kind of cleaning system that it uses. The Germguardian AC4825E would be a good example to start out with because it\u2019s not as expensive, and is loaded with features that are sure to get the job done. Is it the best UV air purifier? Not quite, but it is reliable, and of good build quality.\r\n\r\nWhy We Like It - Germguardian AC4825E\r\nThe medium sized Germguardian AC4825E air purifier is pretty much a decent unit that comes with a True Hepa filter, a UV light bulb and as well as an activated charcoal filter. The True Hepa air filter captures dust particles, pollen and even airborne bacteria to keep the air clean, and is very much energy efficient to keep your energy costs low.\r\n\r\nPower\/Speed\r\nThe Germguardian AC4825E will efficiently serve an area or room size of up to 167 square feet, so it is best suited for smaller rooms. The air purifier features a 3-in-1 air cleaning process, where it incorporates 3 cleaning methods to purify your air. It\u2019s got a pre filter which combines with the activated carbon filter to get rid of large particle pollutants like dust pet dander mould and bad odours, a True HEPA filter to capture particles smaller than 0.3 microns in size, and a UV C light bulb to kill airborne bacteria. This system is pretty similar to what you\u2019ll find with the Pure Enrichment PureZone Elite 4-in-1 air purifier, but what it has that the AC4825E lacks is an ionizer.\r\nEfficiency\r\nThe AC4825E Germguardian air purifier is very efficient in terms of energy consumption, and this is depicted through its energy star rating. Its CADR to watt ratio is pretty good, and to make it consume even less energy, you can even choose to have it run on the lowest fan speed. It\u2019s UV C light bulb is also very much energy efficient, and if you choose to run the UV light only, you\u2019ll end up significantly reducing your energy costs.\r\nVersatility\r\nThe use of a HEPA filter, an activated charcoal filter and UV light is as versatile as the Germguardian AC4825E will get. The only thing that it\u2019s missing that more expensive options such as the Silveronyx Air Purifier have is an ionizer. Other than that, the filter has pretty much the same functionality, and is able to deliver this at a much more reasonable price.\r\nDurability\r\nCovered by a 3 year warranty, the Germguardian AC4825E doesn\u2019t really match up to the 5 year warranty that you\u2019ll get with the pure enrichment purezone air purifier, but it\u2019s still pretty much a worthwhile investment.\r\nValue\r\nRetailing at under $100, the Germguardian AC4825E represents good value for your money, and is of pretty good build quality. It\u2019s also well designed, but the lack of smart features like air quality detection might deem it unfit for use by some people. You will have to replace the filters after about 4-6 months of use, and to do so, you\u2019ll need to go for the filter B replacement and the carbon pre filter pack. They\u2019re also both available on Amazon.\r\nGermguardian AC4825E Wrap Up\r\nGuardian technologies is one of the many up & coming US companies that are doing pretty well in their sales of air purification units. In 2018 they recorded over a million sales of their products, and as time goes on, they only continue to do well as a manufacturer.
