Why a 2-in-1 unit is a wise investment

There are a few reasons to get a 2-in-1 air purifier and humidifier combination unit. The first is that these products can cost quite a bit when purchases separately. Though some of the combo units can be a bit pricey, it is possible to find one that gives you the best of both worlds at a decent price. For instance, the OPOLAR EV01 costs less than $100, which is a great deal when you consider that it is purifying the air and humidifying it at the same time.

Another benefit of the combo machines is that they take up half the space. If you have two separate units, you need room for both of them, which can be tricky if you have limited space in your home.

These products also come with all of the features you’ll find on separate units, including multiple fan speeds, humidistats, and fragrance containers, plus require less maintenance over time.

Features to consider while choosing a humidifier and air purifier combo

If you’re considering adding the best humidifier and air purifier combo to your home or office, there are a few features you should take a look at. This will ensure you have the right model for the air quality, humidity levels, and the size of your home.

Water tank capacity

The water tank capacity can vary from model to model. For instance, the water tank in the Venta LW15 can hold up to 1.4 gallons of water, while the DREVAL D-950 only holds 0.5 gallons. The smaller tanks are fine for smaller rooms or areas where you won’t be running the humidifier all the time. These are also quicker and easier to fill, especially if you’re taking the tank to the sink and back.

The larger tanks can run longer, due to the higher tank capacity, but are heavier to move around when it comes time to fill it up.

Runtime

The runtime of these types of machines refers to the humidifier area, not the air purifier part of the combo. It also depends on a few different factors. The size of the tank is one thing that determines how long the humidifier will run since smaller tanks will run out of water quicker than a larger tank. Of course, the tank alone isn’t the only piece you should consider.

If the machine you choose has multiple speeds, this will also affect the runtime. Running your machine on high all day will go through the water in the tank much faster than if you’re using it once in a while. The lower speeds also won’t use up the water as quickly, so if you keep the fan speed on the lowest setting, it will increase the runtime of the machine. This is why the runtime on most brands is a bit vague, like the BONECO W200, which lists the runtime as “up to 12 hours”. This is the longest the machine will run at the lowest speed.

Coverage area

The coverage area of a humidifier and air purifier combo is one of the most important features to look at. This is because buying a model with a coverage area that is less than the size of the room you’re using it in will keep it from working properly. It won’t be able to put out enough moisture to fix your dry air issues, plus it won’t be able to clean the air of the impurities as well as if it was in a room that matched or was smaller than the coverage area. Before you buy one of these machines, be sure to measure the room or apartment you’ll be using it in and buy a machine with a coverage area that is the same or larger than those measurements.

Speed settings

The speed settings cover both functions of your new combo machine. There are usually at least two or three, labeled low, medium, and high, or some variation of these. This tells you the speed of the fan, which pulls the air in and then sends it back out again.

The faster the fan rotates, the quicker the air in the unit will be cleaned and purified. This setting is best for rooms that are particularly dry and full of unwanted particles in the air. Once the air is cleaned, you can adjust it to a lower speed to maintain the air quality. This way, you can set it as needed, depending on the day or season.

Air purification technology

When it comes to air purification, you’ll want to look at the type of filtration system that is included with the model you’re buying. Some of the models we’ve reviewed here use replaceable or washable filters. These can include pre-filters, HEPA filters, charcoal filters, and even honeycomb filters. Though they all take the nasty particles out of the air, some do a bit more than others. For instance, pre-filters take out the largest particles, like pet hair. HEPA, cotton, or foam filters take out quite a bit more, adding dust, pollen, and pet dander to the list. Charcoal filters get rid of the household odors from cooking and pets.

There are a few other technologies out there as well that are a bit more modern. Ionizers, like the one in the bblüv Ümi Ultrasonic Humidifier + Air Purifier, produce positive and negative charges, which attracts the particles in the air and neutralizes them. UV lights also sterilize the air, getting rid of bacteria and germs that could cause an illness.

Dimensions

If you have a home with a lot of open space, you can likely get an air purifier and humidifier combo of any size without causing an issue. Of course, if you have smaller rooms with limited space, you’ll likely want a model that won’t require you to sacrifice too much of your living space.

Some people also prefer to keep their machines on a counter or bedside table, which means you need a unit that will fit in the space you have available. That’s why it is so important to check out the dimensions of the machine you’re buying. Some of them are square, while others are tall and thin. To be sure you have one that will fit where you need it, measure the space first and get a model with the features you want that fits in that spot.

Warranty

The warranty is extremely important for any of the products you buy. Humidifier and air purifier combos are no exception. If there is some sort of issue with how the machine is working, this could be due to improper manufacturing or faulty pieces. The warranty ensures you don’t need to pay for costly repairs or a whole new unit.

Since so many different brands have varying warranties, you should always check this feature out before you buy, so you know exactly how long you’re covered for. The bblüv Ümi Ultrasonic Humidifier + Air Purifier only has a 90-day warranty, so if any issues show up after that, you’ll be paying for them out of pocket. The Venta LW15 has the best warranty of all the products in our reviews, covering you for a full ten years, so you’ll have plenty of time to test out your unit for any problems.

Extra features

There are also a number of extra features that make some of the models available a bit more convenient to use. One of these is an auto shut-off for the humidifier. When the tank runs out of water, it shuts itself off instead of continuing to run on empty. This prevents damage to the unit and tells you it needs a refill at the same time. Some models also have an alert beep and an indicator light as well.

A timer allows you to choose how long you want your humidifier and air purifier combo to run and shuts it off when the time limit is up. LCD displays show you all the settings you’ve chosen, like the fan speed, timer, humidity level, and water level.

Another thing you may want to look for is a built-in humidistat. This monitors the humidity level in the room. You can set your unit to humidify it to a certain level and the machine adjusts the fan speed accordingly to reach and maintain that level.

How to maintain your new appliance

Maintaining your air purifier and humidifier combo is important to keep it running well for a number of years. The following tips will help you with this:

  • Read the instruction manual before operating your unit
  • Change or wash the filters regularly
  • Clean the water tank regularly to prevent bacteria and mold
  • Wipe down the inside of the machine
  • Only run it as long as specified to prevent overheating
