GermGuardian AC5350B Features and Specifications

It is of rather stylish design and it fits most rooms easily, at least regarding the design.

GermGuardian AC5350B power consumption is rather low and at maximum fan setting, unit draws ~0.5 Amps.

Power cord length is 6 feet (~1.83 m) and is long enough for most situations, although somewhat longer power cord would be nice.

GermGuardian AC5350B is simple to use and maintain air purifier. It lacks some advanced features like WiFi connectivity, but this is often not seen as 'cons', but more like 'pro' - some users simply don't want 'advanced' features, appreciating the simplicity and ease of use.

GermGuardian AC5350B console is simple and straightforward. Controls include:

- On/Off control: it turns the unit 'on' and 'off'.

- Fan speed mode: '1' is the lowest speed setting, but also very quiet. '5' is the fastest speed setting, allowing the unit to quickly purifier air in the room. Default setting is '5'.

- UV-C on/off: turns the UV-C light 'on' and 'off'. UV-C light irradiates germs and kills them, but it also creates very low amounts of ozone. Although ozone levels created by GermGuardian AC5350B are below safety levels, UV-C lamp cam be simply turned off.

- timer: GermGuardian AC5350B features timer, allowing the user to set how many hours will air purifier operate. user can select between 1 and 8 hours.

Note: many users simply turn on the unit and leave the fan on '1' or '2' and forget about it until it is time to clean or replace air filters. This way, unit constantly purifies the air, keeping its quality high all the time. GermGuardian AC5350B is simple to use and maintain air purifier, but just in case, when the unit arrives be sure to read the manual/instructions thoroughly.

GermGuardian AC5350B Clean Air Delivery Rate (CADR ratings) are 108 for smoke, 127 for pollen and 114 for dust.

Note: CADR ratings are measured using brand new air filters and fan set to maximum speed. When the fan is set to the maximum speed, GermGuardian AC5350B filters air up to 4x per hour in the room up to 167 square feet.

GermGuardian AC5350B Air Purification System

In order to achieve desired level of air purification, GermGuardian AC5350B combine mechanical air pre-filter, activated charcoal filter, high performance true HEPA air filter, and UVC lamp with titanium dioxide (TiO2).

Unit features air filter indicator to signal the user that it is time to replace the air filter, which is usually every 6-8 months. Since air purification depends on the quality of air filters, it is recommended to use only original (OEM) spare filters.

germguardian ac5350b filters

GermGuardian AC5350B uses two types of air filters, both of which combine activated charcoal air filter and true HEPA air filter in one unit, simplifying the filter replacement.

First type of air filters is GermGuardian FLT5000 HEPA GENUINE Replacement Filter C for AC5000 Series Air Purifiers.

GermGuardian FLT5000 filter consists of:

- activated charcoal air filter which captures odors from cooking, smoking, pets and other common household odors. Also, it acts as a pre-filter to capture large(r) particles, protecting the HEPA air filter.

- true HEPA air filter captures 99.97% of 0.3 microns or larger particles, like dust, mold spores, plant pollen, pet dander and other common allergens.

Second type of air filter is GermGuardian FLT5250PT HEPA with Pet Pure Treatment GENUINE Replacement Filter C for AC5000 Series Air Purifiers

GermGuardian FLT5250PT is very similar to GermGuardian FLT5000, except that GermGuardian FLT5250PT also features 'Pet Pure Treatment', which is an anti-microbial agent added in order to inhibit the growth of mold, mildew and odor-causing bacteria on the surface of the air filter.

Note that charcoal air filter can be replaced without replacing the HEPA part of the air filter. Since the charcoal filter acts as pre-filter, changing the charcoal filter can prolong the operating life of the HEPA air filter.

Charcoal layer/pre-filter replacement or not? If you have issues with smoke and odors, get yourself a GermGuardian FLT28CB4 4-Pack Charcoal Filter and replace it as required. If you don't have special issues with smoke and odors, and you don't have to change air filter more often than every 6-8 months, personally, there is no need to bother yourself with charcoal pre-filter replacement.

Since GermGuardian FLT5000 and GermGuardian FLT5250PT air filters are intended to last 6-8 months, and although FLT5250PT costs slightly more than FLT5000 air filter, personally I would recommend FLT5250PT.
