Now let’s talk about the features in detail.
In-depth Review of Inofia Air Purifier:
Let’s talk about the filters first. It includes two sets of combined HEPA with activated carbon filters for air cleaning. There are no other filtration techniques included, like ionizers or UV-C lights. Also, it doesn’t have any pre-filters.
HEPA filtration: Inofia comes with true HEPA filter that can easily trap larger allergens like pollen, dust pet dander, mold spores to smaller pollutants like smoke and bacteria. HEPA has the capability of removing particles of 0.3 microns at a 99.97% rate. So, the air purifier can trap all kinds of airborne pollutants that are sized down to 0.3 microns.
Activated carbon filter: Activated carbon filter packed with HEPA filter, and it acts as the second step filtration. Inofia didn’t tell details about the number of activated carbon pellets they used in the filters though it looks pretty thicker. This thick activated carbon filter layer will help you to trap odor from smoke, cooking, pets, or a paint job. This filter got saturated quickly than the HEPA filter. Since the activated carbon is packed with HEPA, so don’t select it if your primary concern is removing different types of odors frequently. Because after 2/3 months, the capability will decrease, but the HEPA might have a couple of months left. So, your filter replacement cost per year will rise.
The air purifier didn’t use any other filtration techniques, which are not necessary basically. But, it has no pre-filters before the HEPA filters rather than the filter covers with large air vents. This is a downside for HEPA filter life as the HEPA filters are not washable. A pre-filter trap larger pollutants like pet hair, dust and it can be easily cleaned, which prolongs the primary HEPA filter efficiency.
Yearly filter replacement cost is almost $160 based on usage. As the cfm is very high, the replacement cost is reasonable for two sets of the filter. Although it’s a rough calculation as the filter life depends on the usage per day and the room air quality. Check the latest filter replacement cost of Inofia 1539 air purifier on Amazon.
Clean Air Delivery Rate (CADR) with Air Changes per Hour: The clean air delivery rate or CADR is 330 cfm or cubic feet per minute, which is very high compared to others in its pricing category. You will get almost 5 air exchange in a massive 500 square feet room. For allergy suffers or smoke removal, it will help in a bigger room. You can find out the cfm needed for a particular reason in your home with our CADR Calculator. AHAM does not verify the CADR though it’s not necessary.
Particle sensor, automatic mode: Inofia air purifier comes with a built-in particle sensor that counts PM 2.5 on the surrounding air. In automatic mode, it adjusts the fan speed based on the surrounding air quality. As the particle sensor located at the bottom of the backside so that it might sense the air slowly because of the lower air circulation. Most of the modern air purifiers put it on either side.
Wi-fi Connectivity: You can pair it with the native mobile app via wifi so you can monitor the air quality and control the air purifier remotely. Though the app support is very poor and you might not like it. Don’t select it primarily for the wifi control feature.
Manual Control: Manual control is excellent otherwise. It has a wide 5 fan speed control and the timer with a 1-hour interval. The sleep mode dims the lights on LCD. It also features a child lock to avoid any unwanted keypress.
LCD: It has a beautiful display on the front with an LED color band around it. The LCD shows the particulate matters (PM2.5) count, temperature, and relative humidity. It also displays the filter life in a bar indicator. The temperature shows on the Celcius scale, and there is no option to change it to Fahrenheit, which is a downside for USA users. Although, most of the air purifiers don’t have built-in temperature and humidity sensors. Air quality (AQI) shows a color LED ring placed around the LCD.
Noise: The noise level on the lowest fan speed is 27 decibels, and the maximum level is 52 decibels on the highest fan speed, which is reasonably good. As it has 5 fan speed, and you can easily set it to a pleasant noise level. Up to 3rd fan speed, its noise is pleasant. Check out the best quietest air purifiers review.
Energy Consumption: The rated power 61 watt, which is very reasonable for this high cfm air purifier. A daily 12-hour usage at the highest speed will cost not more than $2.6 in a month based on 12cents per kWh energy rate. You can calculate your bills according to your usage and the local energy rate with our Energy Consumption Calculator.
Recommendations to select Inofia 1539:
Warranty: Inofia offers 2 years of warranty, which we think is fairly enough.
