Should I Buy a FAD504DUD or FAD504DWD?

Are you wanting to know the differences between the FAD504DUD and FAD504DWD as well as which one offers the best value? If so you have come to the right comparison guide. It is known that the Frigidaire range of dehumidifiers is a well-respected one as the products constantly perform well and give the user exactly what they’re looking for; but, like these two products within this range -- you do come across very similar models.

This in turn can leave potential buyers a little perplexed as to which one they should purchase. So here in order to make things a little easier for you, this article will help you to understand the difference between the Frigidaire FAD504DUD and the Frigidaire FAD504DWD dehumidifiers.

Size: When it comes to the difference in size, it's clear to see the two dehumidifiers are virtually indentical in size; the DWD model is just 1/20 inch taller and 1/50 inches narrower. Not really visible to the eye, so you would need a tape measure to see the difference between them.

Weight: With regards to the shipping weight of each dehumidifier the Fridgaire FAD504DWD (the newer & updated model) is heavier than the 504DUD weighing in at 1.5 pounds more than the older model.

Wattage: Every time the dehumidifiers absorb 50 pints of water, they use up energy. This energy usage has been recorded in watt hours, and as you can see from the table above, the 504DUD consumes 294 watts per hour and the 504DWD consumes just 254 watts per hour of running time.

This may also be because the 504DWD is a later model, and manufacturers have attempted to give their product a greener image by increasing the efficiency of their products as they continue to develop them. This is an energy saving of about 20% so is quite significant, especially with the way that energy prices are rising year on year (way ahead of inflation).

Continuous Run: The 504DUD model does not run continually and will switch itself off after a specified amount of time. 504DWD model is designed for continuous running, which means if your room is damp it is sure to get rid of the excess moisture. As far as energy usage goes, this model is more efficient than its older counterpart, but the user may need to turn it off in order to ensure it does not consume more energy than it ideally should. The benefits of having continuous run is if you have a drain nearby, you can leave it running for a few days while the house is unoccupied, as in the event of a flood.

Integrated Casters: Both models of Frigidaire humidifiers come with integrated casters, which mean they can be pulled or pushed along to the desired area. The 504DWD model is slightly heavier than its older counterpart, but the strong and effective casters should make light work of the unit and enable the user to push it along a flat surface fairly easily.

Fan Speeds: The Frigidaire 504DUD and the 504DWD come with 2 fan speeds. This is ideal if you do not have a lot of moisture in your bathroom, as the lower setting can work more slowly and efficiently for you, without the unit over-heating. If the air in your bathroom contains a lot of moisture, the higher fan setting will ensure it is removed as quickly as possible.

Warranty Information: they are backed by a one year limited coverage plan that includes parts and labour costs and then a further 5 year warranty on the sealed system (all from the date of your original purchase).

Further Information: both operate on a 'low temparature', they provide you with a 'full' indication, digital humidity reading, filter check, anti-bacterial filter and has an (24 hour timer) auto-shut off feature (when the water tank is getting full, as it due to be emptied). Moreover, both are Energy Star certified. Electrical Components: operate on 4.8 Amps and 530 Watts (cy in the case of the DUD). 

 Conclusion: Should I Buy a FAD504DUD or FAD504DWD?

From user/customer experience both models are very well regarded -- however when it comes to comparing the two dehumidifiers, it is clear to see that the Frigidaire FAD504DWD is the more efficient model and works continuously until there is absolutely no moisture left (getting rid of bacteria, preventing mold growing etc.) within the air. Moreover, throw in the fact that it's cheaper and is more economical run too, you can see why the DWD model is the clear option to go for between the two. 

Furthermore, if you have any questions, comments or concerns regarding the comparison of the two dehumidifiers: FAD504DUD Vs FAD504DWD or about either model specifically then please do not hesitate to make  them in the comments section that you will find just below and we will be sure to get back to you as soon as possible.
