Levoit LV-H134 has many standard features that we see among other air purifiers, but it also has some cool features of its own. And being designed in California gives additional credibility to this product.

True HEPA Filter

When buying a premium air purifier, you should focus on this feature.

All premium air purifiers should have one type of true HEPA filter. True HEPA filter guarantees that the air purifier is capable of removing 99.97% of airborne particles.

That is also the maximum possible air filtration performance, and because of that, it is crucial to check if the air purifier is labeled as a true HEPA air purifier.

Preliminary Filter and Activated Carbon Filter

Every air purifier with a True HEPA filter has a preliminary filter; some of the models have washable prefilter while others have removable.

That is not important as long as the preliminary prefilter does its job and that is removing large particles from reaching a true HEPA filter. In that way, a true HEPA filter will be working at maximum capacity for a longer time. 

The activated carbon filter is essential for removing bad smells, smoke, and other unwanted odors in the room. The size of the activated charcoal filter is important since the larger it is, the faster it will remove bad smells. The activated charcoal filter is replaced together with the true HEPA filter and probably won’t need a sooner replacement.

Levoit LV-H134 is Full of Options

This Levoit air purifier is made for all types of customers. Older ones who are not familiar with all the fancy options this air purifier offers can set the auto mode on and relax. On auto mode, the air purifier monitors air quality and then sets the proper fan speed for optimal air purification.

For advanced users, there are many options. You can place an air purifier in sleep mode at night. The air purifier will work at the lowest possible speed and will not make noise that will wake you up. 

You can also adjust the speed manually. And if that is not enough, then you can set up a timer, and an air purifier will filter a room for a desired period of time. You can choose between 1h and up to 12h.

Real-time air quality monitoring is probably the best option this air purifier has. Only a few air purifiers on the market on this budget level will give you the option to watch air quality in real-time. The blue color is telling the air quality is very good, green is still good air, but orange is showing some pollution in the air, while red means that the air quality is bad and you should use the highest possible speed to filter the air as soon as possible.

A filter indicator is also an excellent option that is extremely useful to have. As soon as the filters are not working properly or are dirty, you will be alerted on display to replace filters as quickly as possible. Usually, filters last about six to eight months it all depends on how often the air purifier is working and how high is the pollution in the room.

Large Room Air Purifier

Levoit made LV-H134 for a large room. That means that the most value you will get by placing the LV-H134 air purifier in a room as large as 710 feet.

But that does not mean you can’t use this air purifier in smaller rooms. In smaller rooms, the air purifier will work better while if you place it in a larger room than 710 feet the work of LV-h134 will not be the best especially if there is high pollution in the room.

Maybe you should consider getting a different Levoit model LV-H126, LV-H132, and LV-PUR131. LV-H126 and LV-H132 are ideal choices for small rooms or offices.

Energy Efficient

With this air purifier, you won’t notice any changes in your electricity bill. It consumes only 45 watts when working at full speed. On standby, this air purifier is consuming less than one watt. 

Replacement Filter

You should always use original replacement filters because that is the only way to make sure the air purifier is working at the best performance possible. The good news about LV-H134 is the affordable price of replacement filters. The cost of the replacement filter is less than 1/3 of the original air purifier price.
