Air Purifier and Humidifier Combo

C lean, healthy air is essential to creating an ideal living environment. Alas, it is impossible to enjoy this perk without the use of specialized devices as our homes, no matter how hard we try to keep them clean, are plagued by health-threatening pollutants like volatile organic compounds, mold, dust mites, and even bacteria. This causes respiratory issues to arise in healthy individuals and it puts those who suffer from allergies or asthma in a truly unpleasant situation as their afflictions act up due to the improper habitat. If the situation wasn’t bad enough on its own, there’s the humidity level issue to think about as well. As the seasons change, so do environmental conditions, and the dry air that is present in wintertime predisposes you to colds, nosebleeds, dry skin, and chapped lips.

To keep the situation under control, you would normally require the help provided by 2 different devices – the air purifier that tends to remove airborne pollutants, and the humidifier that tackles low humidity by outputting moisture. But why should you make two separate purchases when you could fix the issue with a single device? Although the market isn’t saturated yet and there is room for improvement, there are more than enough qualitative air purifier and humidifier machines that are sure to serve you properly, creating that healthy indoor environment you always dreamt of.

Frequently Asked Questions

Performance Q&A

?It is as performing as separately purchased purifiers and humidifiers are?
The answer to this question varies depending on the specific product at hand as some models are equally if not higher performing then their individual counterparts, while other models are indeed less performing, not being able to increase moisture and remove contaminants with the same effectiveness provided by separate devices.

?Will it help eliminate bad odors?
Generally, issues related to bad odors indoors are fixed with the help of an activated carbon filter that is specifically designed to absorb the particles which cause the appearance of the odors to start with. Thus, if you want to target bad odors, we recommend you opt for a model that features this filtration media.

?What are the health issues it helps prevent?
Seeing how it performs not one, but two separate functions that both collaborate to create safer and cleaner air indoors, there is a wide range of health issues it prevents. Among the most important issues it keeps at bay are included congested sinuses, dry skin, dry hair, skin irritations, colds, allergies, asthma attacks, and other types of respiratory system problems.

Maintenance Q&A

?How often is filter media replacement required?
This depends on the specific model at hand, some systems requiring it more often than others. There are systems that use different methods to rid the air of impurities, not relying on filters, which obviously don’t require this maintenance procedure. If your pick does feature filters, however, you should check the user manual or spec sheet to see when and under what circumstances you will need to make the change.

?For models with a water tank, what type of maintenance is needed?
It is preferable that you take out the water tank and thoroughly clean it using a vinegar and water mixture once per week. Otherwise, you risk for bacteria to form in it and for the device to start releasing impure moisture into the air, thus putting your health in danger as you inhale these harmful contents.

?What happens if I don’t refill the water tank on time?
If you don’t refill the water tank on time and the system doesn’t feature an automatic shut-off set in place for this specific occasion, you might end up overheating the device and rendering it useless. On the bright side, all quality systems come with this safety feature in place to prevent this occurrence.

Other Questions

?Does the risk of over humidifying the air exist?
Yes, this risk does exist, and you must avoid over humidifying the air at all costs as it leads to the appearance of mold and mildew, their spores presenting a great threat to your health when inhaled. To make sure this won’t be an issue, only use the humidifying function until indoor moisture levels reach 60%. Never let moisture levels exceed this limit as a perfect growing ground for the aforementioned pollutants is created.

?Is it more energy efficient than separate devices are?
Considering the fact that instead of running two separate devices you will operate a single unit, it is safe to say that, regardless of how much power it draws, it is still more efficient in terms of energy consumption than a separate moisture increase device and air cleaning device would be.

?What are the features/specs that matter the most?
As it is supposed to fulfill two totally different functions, the specs and features you must be on the look for involve both functions. Make sure that the system is able to remove as many airborne pollutants as possible, preferably over 99% of them, and that moisture output per day is as high as possible for dryness level to be fixed fast.
