Cons / This air purifier has the worst CADR scores out of all the purifiers we reviewed, meaning it is less effective at removing indoor pollutants from your home.
Verdict / The Heaven Fresh NaturoPure is conveniently sized, but it lacks a few helpful features and the air-cleaning power of the best air purifiers.
The Heaven Fresh NaturoPure is an air purifier with a five-stage purification process, although it doesn't have impressive CADR scores or the certifications we look for. This air purifier is the smallest we reviewed, making it easy to move from room to room as you need.
This air purifier uses a five-stage filtration system that includes three filters and two potentially harmful or even useless technologies. The HEPA filter is designed to capture small particles, ranging from smoke to pollen particulates. The carbon filter reduces strong odors, as well as chemicals and gases. Next, the air purifier uses a TiO2 filter, which is activated by UV light to destroy bacteria, mold and other organic pollutants.
The machine also has an ionizer that charges particles as they pass through the system to make those particles easier to catch on the next pass. Note that ionizing technology has been scrutinized by the EPA for its effectiveness and potential side effects. For this reason, many purifiers with ionizers allow you to turn the ionizer off, but the NaturoPure does not.
Finally, the Heaven Fresh NaturoPure uses a UV light to attempt to destroy a number of microbial contaminants. Although UV purification is used in a number of scientific and medical procedures to sterilize equipment, this is a lengthy process in which the desired object is exposed to UV light for quite some time before it is considered sterile. So although this air purifier uses UV light to try to destroy pollutants, it pushes air through at such a high rate that particles are barely exposed to the light and don't have enough time to be purified. As such, this method of air purification for home air purifiers is generally considered useless.
Unfortunately, this five-stage purification process results in a machine with the lowest CADR scores on our lineup. This means that the Heaven Fresh NaturoPure is the least effective at removing indoor pollutants from your home, including dust, smoke and pollen. According to AHAM's formula for appropriate room sizes, this air cleaner effectively cleans the air in rooms up to 256 square feet, which is significantly smaller than the company's specified room size of 430 square feet.
The NaturoPure lacks a couple of convenient features. It doesn't have an operation timer that allows you to set it to run while you are away. It's also missing a remote control, which would add an extra layer of convenience. However, it does include a couple of helpful operation modes to make the machine easier to live with. First, the purifier has an auto mode that detects the level of pollutants in the air and automatically adjusts its settings to clean the air effectively. You can also take advantage of the sleep mode, which reduces the fan speed so it won't disturb you while you sleep and saves energy.
This is the smallest purifier we reviewed, so it is easy to move from room to room as you need. However, detracting from the ease of use is the somewhat confusing control panel with only two buttons and few settings. Eventually, using the quirky control panel becomes second nature, but it takes a little practice. Another potential drawback is that it lacks certifications from Energy Star, AHAM, ARB and UL. This means it may not meet certain industry standards in energy efficiency, safety, testing methods and effect on air quality.
In case you have any problems with your NaturoPure, it is backed by a three-year warranty that covers most repairs. Heaven Fresh's website gives you several ways to contact customer support, including telephone and email. You can also contact a customer support representative through live chat, which is very convenient. You can download the user manual from the product page and view FAQs as well.

The Heaven Fresh NaturoPure's five-stage purification process ultimately results in extremely low CADR scores. This means this air cleaner is the least effective at removing indoor pollutants from your home among the models we reviewed. This purifier has a small, lightweight design that makes it easy to move around the house as you need, but it lacks the power, efficiency and certifications of the best air purifiers.
