best air purifier for the price

Top fill design and easy to clean

We were not going to make a review list of top fill humidifiers without adding a Geniani product. Known for their simple looks and easy to use nature, this humidifier also has a top fill design that makes the refill process as easy as possible. No removing tank, no flipping upside down, just pour in water through the slit at the top.

You can also remove the whole top cover for more refill convenience, and also when it is time to clean. Cleaning is very easy because virtually all parts of the unit become accessible as soon as the top cover is lifted.

Automatic mode and quiet operation

For your convenience, this humidifier is built with a smart mode. In this mode, it maintains the humidity in your home at a healthy level through the help of an intelligent sensor. However, you can still manually adjust its moisturizing speed by choosing either low, medium, or high setting. It is ultrasonic, therefore very quiet while operating, and affords you a sound sleep and zero disturbance.

Although we wouldn’t exactly call it a 2-in-1 device, it is the only other product in this review that supports aromatherapy and gives it a right to the title. It is essentially both a humidifier and diffuser in the same product because it can be used with essential oil. Enjoy the benefits of having a 2-in-1 product with this humidifier.

The unit is a little disappointing in capacity. Although it confidently humidifies the recommended room size, its capacity does not quite match that of others we have reviewed so far. It is only suitable for small rooms up to 220sqft in size and has a 1-gallon tank that doesn’t provide enough for running for a day. It averages about 18 hours on the lowest setting.

  • Fairly large 1-gallon water tank that gives up to 18 hours of runtime

  • It lacks durability and is prone to leakages
  • White dust problems when used with hard water

Features to consider in choosing the best top fill humidifiers

Top fill design:

This article is the most important feature we considered in a humidifier. Products with top fill design make a humidifier easy to use and save you a lot of stress on refilling. This design is very common today and is seen across all categories of humidifiers. Purchase one with top fill rather than an equivalent product without it.

Capacity:

The capacity of a humidifier cannot be neglected too. Although this article is on the best top fill humidifiers, top fill does not humidify the air. A humidifier should have enough capacity to raise the relative humidity of your room. Details to look out for are the room size recommendation, mist output rate, and water tank capacity.

Automatic/ smart mode:

This is a mode that creates the best humidifier experience for users. In smart mode, a humidifier runs independent of your input and automatically manages relative humidity in the air.

Noise level:

Even the largest capacity and best top fill designs but noisy units are a pain in the ass. High noise levels can ruin the quality of a humidifier; therefore, it should always be considered before purchasing one.

What are the benefits of using a top fill humidifier?

Top fill humidifiers have two major benefits. They are:

  • Easy to clean:

With a top fill product, you can easily take off the top cover and gain unrestricted access to the humidifier’s internal parts. This zero restriction makes it possible to reach deep parts that might have been impossible to get to and very easy to clean.

  • Easy to refill:

This is the most obvious benefit of using a top fill product. Many humidifiers require you to detach its water tank and fill elsewhere, or worse, by carrying the whole unit. This process also involves lots of flipping upside down and messy water leakages.

With a top fill design, you can easily top up without any of these stress. Simply pour water in through the opening at the top.

How should you fill a top fill humidifier?

It is easy, detach the top cover, and pour in water. The major obstacle is in figuring out how to remove the top cover because different products have different designs and ways that it should be done.

Most of the time, this instruction is found in the units’ instructional manual, do well to go through it, and you should not have any problem removing the top.

On the other hand, you do not have to remove the cover to refill in some units (like the Geniani product). Units like that have a slit through which you pour in water; therefore, the top has to be removed only when cleaning time.

Also, you must look out for places that water is not supposed to get to. Humidifiers mostly have no go areas for water, and once again, it is always specified in the manufacturer’s instructional manual.

Water getting in such areas could cause the humidifier to malfunction, or worse, the damage it completely, therefore read the manual properly.

Are top fill humidifier better than non-top fill humidifiers?

Speaking in basic terms of what a humidifier should be (moisture-producing machine), we cannot say that top fill products are better than non-top fill humidifiers.

However, we cannot also deny the fact that they are much easier and convenient to use.

If there was a choice to make between a top fill humidifier and a non-top fill humidifier, choose the top fill unit.

Note that this comparison does not consider other features like its room area capacity, mist output rate, run time, and other modern features. In this comparison, we assumed that they both have all these in common and on par.

Verdict

Any humidifier that you intend running for long hours must have the top fill design. This makes your life healthier and easier regarding refills. The best top fill humidifier for you is the KEECOON product.

Asides the top fill, it packs so much quality and modern design that makes it a pleasure to have and a viable humidifier for many years.

Its 1,500ml/h mist output rate is unmatched, and with 1000sqft area capacity, it couldn’t get any better.

The Elechomes Warm and Cool Mist humidifier is also a good product that we recommended as the next best to scale down a little bit. It possesses the warm and cool mist function that is not seen in the Keecoon unit and humidifiers at 600ml/h.

It is suitable for large-sized rooms and comes with other automatic features that give you the best user experience.
