Factors to Consider Before Buying a Filter-less Humidifier
Presently, many makers create filter-less designs as per their increasing demand. Consequently, the market is filled with numerous designs and, therefore, choosing the suitable one for you is tricky. There are crucial features to take into account to ensure you purchase the best design. Take a look!
- The Capacity of the Water Tank.
When purchasing a filter-free humidifier, the water tank’s capacity is a crucial factor to take into account. The device’s efficiency in moisturizing your household solely relies on its water tank capacity.
Besides, you should also know the room size where you’ll be putting the device. It assists you in making a suitable decision.
You should invest in a device that has a big water tank as it implies that it’ll operate for longer periods. In that way, the air is evenly distributed in your room.
- Moisturizing Technology.
There are two main technology types behind humidifiers. Each of them can execute two functions. Ultrasonic humidifiers utilize resonations to produce the humidity that the fan pushes into the room. These models can operate longer, are silent, and cost a bit more.
Using mechanical means, vaporizers change the water into vapor and dissipate the vapor via the nozzle. These designs are somewhat noisy and usually don’t have the visible moisture trail, a characteristic of ultrasonic designs. The two types can utilize chilly or warm mist through heating the water or not.
- Energy Efficiency and Safety.
In any electrical appliance, safety is a primary concern, particularly if that device contains water. Humidifiers should come with safety features and if they don’t have, then get a different design. Among the usual features, is an auto shut-off.
In case the appliance overturns, the water tank is elevated, or the tank gets dry, it’ll switch off automatically. If your humidifier doesn’t have these features, you may be at risk of burning the motor of the humidifier, leading to a fire or a short circuit in your household.
You may also need to check the device’s energy efficiency when possible. Since these are small devices, not much thought is given to efficiency.
- Area of Coverage.
Decide on where you’ll put the humidifier. The room’s size (measured in sq. ft.) can be too big for the humidifier’s capacity you select. Make sure that the humidifier is at least the size of the room or the rooms you intend to use it in.
Here, you should know that bigger isn’t better. For instance, you may generate excess vapor and lead to condensation or high water vapor if you have a bigger capacity humidifier in a small space.
- Level of Noise.
Humidifiers aren’t too noisy, but you can opt for quiet designs or normal models. Many humidifiers range from 50 to 55dB. It’s sufficient volume to have a little noise during the night. However, it can agitate lighter sleepers.
Ultrasonic designs are the quietest as their noise starts from the mid -20dBs. There’s no noise at all from these models, and you can fall asleep in near silence, hold an ordinary volume conversation without hearing the motor’s hum.
- Setup, Maintenance, and User-friendliness.
Many humidifiers are user-friendly. The essentials comprise filling the tank, connecting the device, and switching it on. However, some appliances are more intricate and need a little more knowledge.
Features such as voice-command working or remote control, water vapor level settings, automatic timers, and other special functions may need more directions or set up steps. Not only will you operate your humidifier easily, but you’ll also maintain it fast and effectively.
Maintenance is crucial, and this is something you can perform frequently with ease. Large openings, easily accessible parts for cleaning and machines that can be disassembled are perfect for this maintenance type.
- Additional Features.
Some humidifier firms keep the price lower to lure you to purchase from them. They get rid of some features or don’t include others to ensure the cost remains low. However, several firms add numerous features with the hope that you’ll pay extra for their performance.
Inspect for features such as automatic settings, humidistats, voice-command activation, overflow protection, timer function, remote control, mist output controls, and aromatherapy diffuser. Every feature may add to the general cost, but you can choose the ones you want to pay for.
Lastly, you may want to check the duration and guarantee coverage. Most humidifiers have a 1 to a 2-year guarantee.
However, some can have a warranty of up to five years. You should not only check the duration of the coverage but also what’s covered, when the coverage begins, and what you need to make a claim.
FAQs
In these humidifiers, the water isn’t filtered. Does it imply that the air will be harmful and contaminated?
Filter-less humidifiers can keep the air moist and clean at the same time. The appliance returns dampness to the atmosphere – as a conventional humidifier – it’s only that it works without a filter.
Although the air remains clean, the appliance has no detachable filters. Rather than detachable filters, the device uses electrostatic charge technology, antibacterial materials, and pre-heating (for warm mist designs) to ensure the air is cleaned and broadcast back to the atmosphere in the form of haze.
Can you set the humidifier for the entire night and is it safe and silent enough?
Usually, it gets chilly at night, and the temperature drops, the air becomes drier and so, you may require a humidifier. A humidifier works by restoring water vapor in your room and it’s completely safe.
Is it safe to use a humidifier around kids?
Yes, filter-free humidifiers are safe for use around kids. Like any appliance with electricity and water and moving parts, ensure that it’s out of reach of toddlers. Select a humidifier with an automatic switch-off feature when overturned, lifted, or knocked over if you have small kids or pets.
Can you use tap water on a filter-less humidifier?
Yes, in your humidifier, you can use tap water, although it’s strongly discouraged. It’s suggested that you use distilled or demineralized water. It’ll help your appliance operate smoother, generate fewer allergens and deposits, and ensure the system is devoid of mold, clogs and facilitate cleaning. If you have to use tap water, ensure that you clean it completely after each use.
Where should you put your humidifier in your home?
Where you’ll put your humidifier depends heavily on the device type and size. Many devices work well on the wall or countertop. When choosing a design with a 360-degree spinning nozzle, you may want to find a more central location. The instruction manual provides placement suggestions that are most appropriate for the model you purchase.
Final Verdict
The best filter-free humidifiers are increasingly becoming popular because of their minimal maintenance costs and silent operation. The appliances operate effectively by increasing the humidity in the air to create cozier home surroundings.
Before choosing an appliance you should take into account its effectiveness and how it’ll suit your lifestyle. Also, bethink about whether it’s easy to clean it and if it’ll save you time and effort. Have fun shopping!
