Time to Replace an Existing Fan?

Recently moved into a new property and found your existing bathroom fan isn’t quite cutting it? It’s not an uncommon gripe with new homeowners. No matter how luxurious a bathroom might have looked during those initial viewings, the veneer can quickly fall away when you’re faced with suffering a below-par exhaust fan.

Almost every property has an extractor fan of some sort or other installed, but designs can vary wildly and some are more effective than others. Primary function aside, you’ll want to consider your bespoke bathroom requirements and what other features you might be in need of.

Bathroom Extractor Fan Types

Although all types of bathroom extractor fan should prioritise moisture removal and humidity control, others are more effective in certain spaces than others. A go-to option for many households is a ceiling exhaust fan. These popular models are relatively easy to install in bathroom ceilings and work by drawing air upwards, encouraging it to dissipate through your roof. In certain cases ceiling fans may be connected to ducting instead, with the drawn air expelled through a vent.

An alternative to this design is an inline exhaust. If you’re limited with space, this can be the best extractor fan option for keeping moisture to a minimum and improving ventilation. Effectiveness can vary with inline exhausts, but they do have the benefit of being relatively quiet when compared to conventional ceiling fans.

Seeking something simple and effective? Wall mounted bathroom fans might be just what you’re after. These effective exhausts are fitted on the wall of your home, forming a simple channel for moisture and humid air to be fed through. Many contemporary exhaust fans may incorporate some design elements from various types, providing versatile alternatives for more demanding spaces that require a multi-pronged approach.

Buying a Bathroom Exhaust Fan – Things to Consider

If you’re a novice when it comes to bathrooms behind-the-scenes, deciding on which exhaust fan to go for is a tricky challenge. Remember what the core functions of an exhaust fan are and be wary of manufacturers trying to oversell something incredibly simplistic as standout.

When deciding on which fan is right for you, the main consideration you should keep at the forefront of your mind is ultimately the size of your bathroom. You’ll want to know the fan you plump for is fit for purpose and can adequately ventilate your space. If you’re lucky enough to have a particularly large bathroom, you may want to consider investing in multiple fans to ensure better coverage across your square footage, rather than settle for a mammoth-sized main unit.

Easy Installation

No matter whether you’re looking to install your new extractor fan yourself or bring in outside help to get the job done, an easy installation is always welcome. When wiring a fan, you don’t want to worry about ripping apart ceilings or walls, for example.

You’ll also want to make sure you double check to see what’s included with your exhaust unit. It definitely makes life easier if you’ve purchased a unit that comes with all the necessary mounting and fixing essentials needed for a fuss-free installation.

Noise Levels

People often overlook the noise levels of exhaust fans until a unit has been fitted and it very quickly becomes a daily problem. Even someone who thinks a noisy operation is a fair trade off for performance will no doubt end up eating their words in little time at all. Noise is particularly important in households with multiple occupants, especially if routines aren’t in sync. If someone has to be up at 5 every morning and in the shower moments later, an exceptionally loud exhaust fan is going to rile a houseful of friends or family members looking to linger in bed for another few hours.

In terms of bathroom exhaust fans, noise rating is measured in ‘sones’. Check to see what the rating is for any prospective exhaust purchase for a simple guide. Generally speaking, anything rated 2 sones or higher will likely prove too loud to live with.

In Conclusion

There’s certainly a healthy range of options on the market, but after sifting back through our best bathroom fan shortlist, we think there’s a clear standout. The Xpelair C4TS Simply Silent Contour Extractor Fan has plenty of first-rate features and impressive functionality, but that whisper quiet motor and noise-suppressing technology really lets this one shine. There are a great many extractor models on the market today promising close-to-silent showers, but that’s all too often balanced out by below-par operation and extraction rates that leave a little to be desired. You won’t find this kind of compromise bringing the Xpelair V4TS Simply Silent down.
