GermGuardian 4-in-1 Air Purifier: True HEPA Filter, UV-C Light Sanitizer, and Traps for Dust, Pollen, Pet Dander, Smoke, Mold, and Odors

W. Hohauser: Bought this to eliminate recreational smoke coming in from a neighboring apartment into our small kitchen. Small enough to place on our refrigerator and reach the front controls unlike other small air filters that have the controls on the top which would be impossible to get to on a refrigerator. Works well but the fan is loud even at the low speed, 47db according to my sound level app. Fortunately the sound isn’t terribly annoying when it’s on and an hour is enough to clean the room’s air again. Can’t tell if the UV light is on at all. Our other Germ Guardian filter has an LED indicator showing the UV light on. Not sure I would recommend this except in specific situations.

smallwaistbigpackage: Just, wow! I had previously purchased a Germ Guardian pluggable air purifier for my bathroom. Honestly, I left a review on that one about a year ago. I had no complaints except I couldn't tell if it was actually working...

This product though from Germ Guardian is another level! It's very simple to operate with just one button (the ionizer) and a click-wheel to get through the different fan settings (fan speed). You can immediately SMELL this thing is working, and it's working big time! I have never encountered such a well made air purifier before.

There is some white noise with this machine, but it blocks out other sounds when I use it to sleep so I don't mind. It saves me sinus and headache and allergy medications and issues! The air smells fresh, crisp, and CLEAN! Again, honestly wasn't sure if this item was going to deliver in terms of performance; however, it far exceeds my expectations!

Note: the air does blow out at an angle - probably 45 degrees - it does not blow out straight. I'm not sure of the reasoning behind this, but just a minor inconvenience.

Overall, extremely well made product that has helped my health...

Isel: Excelente artículo lo uso de 4-6 horas continuas en mi salón de clase y el medidor me muestra un excelente ambiente despejado a pesar de tener clases continuas con 25 alumnos hasta el momento
Me encanto y lo volvería a comprar

Paras S.: Very bad quality

GABOGABO: PROS: Consigues fácilmente los filtros, no son caros comparados con otras marcas. Siempre revisa eso, porque de nada sirve un purificador al que no puedes cambiarle los filtros.
Tiene un foco ultravioleta que elimina los virus en el aire.
Al aventar el aire de frente ayuda a refrescar el cuarto como casi como un ventilador... a diferencia de otros que lo avientan hacia arriba.

CONTRAS: Ruidoso, similar a un aspiradora, a un horno de microhondas
Es casi imposible darle mantenimiento, para abrirlo es muy complicado a mi me gusta abrir mis aparatos para limpiarlos de polvo y este tipo de aparatos acumulan mas polvo por su tipo de uso. Y para repararlo en caso de falla es igual muy complicado.
Tiene una advertencia del gobierno de California donde indica: "Este aparato puede contener elementos que llevan plomo" (supongo la pintura) ... y eso es la gota que derramó el vaso... por todo lo anterior y encima esto... me había gustado al comienzo pero el no poder abrirlo fácilmente para limpiarlo o repararlo me molesta demasiado.

Cliente de AmazonCliente de Amazon: Compre un purificador debido a que tengo alergias y entra mucho polvo a mi casa por una construcción cercana, debo admitir que fue una compra de impulso sin tanta información, pero al final no tan desatinada

Funciona muy bien, sin embargo este modelo es para cuartos más pequeños, si la ponen en espacios más grandes tendrá poco efecto o tardarán días en percibir una mejora del aire aunque esté encendido 24/7, por eso es muy importante entender las siglas y tablas HEPA qué rigen a todos los purificadores y que dan claridad y guía respecto a su eficiencia para limpiar el aire.
La desventaja qué le encuentro es que es muy ruidoso y un tanto difícil de ignorar.

Claudia: Definitivamente lo recomendaría para personas que sufren de alergia o que viven en lugares con mucho polvo. Yo padezco de alergias y por las noches era peor ya que estaba el polvo acumulado de todo el día en el cuarto. Al usar el purificador, he notado una diferencia y sí se han reducido de manera considerable mis problemas de alergia.

KJ: This product looks aesthetically pleasing and well made, but upon opening the box this is not the case.

I bought a GermGuardian AC4825 in 2014 and I love it. Its literally been running for 2 years. Its not noisy, doesn't vibrate, and just feels like a good quality item. I have no complaints about it.

It seems like GermGuardian has really let quality slip since then. The AC4100 feels cheap right out of the box. The plastic case is thin, doesn't line up right in some areas. The filter guard clip feels like its going to snap off every time I clean it and does not fit snugly against the filter or case.

My biggest complaint is the noise. The motor or fan is very unbalanced and vibrates. I have to keep it on low or I can hear an annoying vibration two rooms away. I had intended to put this on my desk but even on low the whole desk rattles. If I put it on the wood floor with the fan set on high, its felt throughout my whole apartment.
For the last two months its been on a thick foam mat that I cut to size, this helps dampen the vibration a bit but I still hear it on low.
Having used it for 2 months I must say it does filter the air well and...
