Air quality is a very important aspect to consider regardless of wherever you choose to live, and it is something that ought to be taken very seriously especially if you wouldn’t want to catch any respiratory diseases. If you happen to live or work in a place where the air isn’t so clean, then you might need to get yourself an air purifier.

You don’t necessarily need to get yourself the best air purifier around; you just need something that’s got enough power to clean out the air in your room. The Germguardian AC5250PT for example would be great if you had a room size of close to 180 sq. ft., so if this sounds like the size of your bedroom or living space, then it could be the finest UV air purifier for you.

Why We Like It – Germguardian AC5250PT

With a True HEPA filter, an optional UV light, a charcoal filter, and a pet pure filter, the Germguardian AC5250PT is well equipped to make sure that your living space stays free of allergens, and is filled with fresh air.

  • 5 stage filtration process
  • Quiet operation
  • 5 Year Warranty
  • No 24 Hour Timer


The AC5250PT Germguradian air purifier boasts of a 5 stage filtration process. It involves the use of a True HEPA filter that gets rid of pet dander, harmful germs, mold spores & other allergens, the use of an activated charcoal filter that reduces odors, a pet pure filter that prevents the growth of mold on the filter’s surface, and lastly, UV C light technology to kill germs & bacteria. The only thing that makes it different from the Pure Enrichment PureZone Elite 4-in-1 air purifier is the pet pure filter and ionizer, but other than that, the two share the same filtration process.


As an air purifier that has a CADR rating of dust (123), pollen (128), and smoke (116), you would expect that the Germguarduan AC5250 air purifier would require a lot of energy to function. This is pretty far from the case, since, unlike the Silveronyx air purifier, the unit actually has an energy star rating, meaning that it’s quite energy efficient. You can also opt to use the lowest of its fan speeds to keep its energy consumption low, or its 8-hour timer to schedule when it should function.


The use of a true HEPA filter, UV C light technology, and a carbon-activated pre-filter is something pretty common to find among most air purifiers. The one thing that makes the AC5250PT stand out is its use of a pet pure filter, which is key for maintaining proper functioning. The Germguardian AC5250PT also has a decent room coverage of 193 square feet, making it suitable for medium to large rooms.

Other models from this brand include the GermGuardian AC4825E, GermGuardian AC5350B, and the GermGuardian AC4825.


Both the Pure Enrichment PureZone air purifier and the Germguardian AC5250PT both have a warranty policy that grants coverage for up to 5 years, and this gives you an idea of the level of trust that the two manufacturers have in their products. If you opt for the AC5250PT, you will always be able to reach out to the customer care team at Guardian Technologies in case of any issues, so don’t hesitate to do so if your unit arrives with any problems. You’re also encouraged to use genuine replacement filters, since getting a generic air filter may reduce the quality of functioning.


With a filter change indicator, you’ll easily be able to know when it’s time for filter replacement, and doing this will be able to ensure that air purification always happens well. The unit also guarantees quiet operation, so you shouldn’t expect to be woken up by any noises from it at night. You’ll also need to make sure that you get the pet pure treatment pack so that you’re able to keep the filter off molds and anything of the sort, and this is something that you can pick up from Amazon alongside the activated carbon filters.

They may not have HEPA or carbon filters, but these two car filters can clean the air in a vehicle quickly: the Frieq car air purifier and the Homdox car air purifier.

GermGuardian AC5250PT Wrap Up

As you have seen in this air purifier review, the Germguardian AC5250PT is arguably one of the best air purifiers around, and it offers very good value for its money.
