While other air purifiers use two or three types of filtration, the Intelli-Pro Air Purifier uses seven: a HEPA filter, an activated carbon filter, an ionizer, a photocatalytic (TiO2) filter, a germicidal UV lamp, a washable pre-filter, and an electrostatic dust collector. The Intelli-Pro’s HEPA filter is proven in clinical air chamber tests to remove 99.97% of airborne particles in areas up to 600 square feet. The activated carbon filter is effective against chemicals, odors, and cigarette smoke, and the UV lamp kills bacteria and other microorganisms. The Intelli-Pro’s reusable collector grid uses magnetic force to trap pollutants and help lengthen the life of the other filters. Sensor Technology Removes Guesswork With the Intelli-Pro, there’s no guesswork, just clean air. The Intelli-Pro’s unique self-monitoring system gives you instant, easy-to-read feedback about the purifier’s performance. A Clean Air Monitor uses indicator lights to let you know how clean or polluted the air is. Additionally, odor, dust, and allergen sensors tell you exactly which pollutants are present in the air, an ideal feature for those with allergies. And thanks to the Intelli-Pro’s Filter Indicators, you’ll never have to worry about forgetting to clean or replace the filters. The indicators illuminate when it’s time to clean the metal dust collector plate or replace the HEPA filter or activated carbon filter. Quiet, Efficient Operation The Intelli-Pro lets you enjoy purified air without noise pollution. The quiet setting provides nearly silent operation, while the high setting provides boosted performance without a lot of noise. As efficient as it is quiet, the Intelli-Pro has a low-volume fan and multiple air inlets for maximum airflow. Additionally, sensor technology automatically adjusts the purifier’s settings to reduce energy consumption. Warranty Information The Intelli-Pro comes with a 30-day risk-free guarantee. Within 30 days of purchase, if you’re not completely satisfied with the purifier, you may return it for a full refund.

What experts didn't like

The seven-step filtration process means a lot of filters to change and a slower airflow output.

The lights on the Surround Air are very bright. This can invasive, especially at night.
- ratingle
Fragile parts. We have observed that this unit is made up of some fragile parts. You therefore have to be careful when taking the unit apart.
- The Air Geeks
It is expensive.
- How to Home
Long term high maintenance costs.
- Soundproofing Ideas
Doesn't effectively filter and purify air in awkward areas of a home or building.
- Air Purifier Smoke
Based on the few discussions that I had with few XJ-3800 owners, the general consensus seem to be more on the positive side of things. But there is one thing that frustrates many of them.It is the odor sensor and odor removal of this air purifier that prompts a 4-star (instead of 5) rating from most of them. You’d never imagine what those guys can think of to test out the odor sensor of their air purifiers.
- Air Purifier Reviews HQ
Not Energy Star certified (Still very low power consumption).
- Home Air Helper
Even though the air purifier provides effective and long lasting performance, the UV lamp is not durable.
- Home Air Guide
Can’t get rid of strong odors – Some customers have noticed that the Surround Air XJ-3800 can easily remove faint odors in the air, but it seems to have difficulty removing stronger scents such as those of tobacco smoke.

An Overview On Electrostatic Air Purifiers

There are pollutants in the air all around you. Whether you’re at home, in your office or spending some time on the lake, you’re breathing allergens throughout the day. If you don’t suffer from allergies or other health conditions, you may not even notice it, but it still affects how you feel. In fact, just breathing polluted air can decrease your lung function and possibly increase your risk of developing health issues.

A good air purifier can help with that. But there are so many different methods of filtration, it can be easy to feel out of your element as you’re shopping. An electrostatic air purifier uses the power of static electricity to attach air particles to the filter. You’ll then be required to clean the filter periodically to keep your purifier’s interior clean.

HEPA air filters, on the other hand, use a disposable filter to capture the particles. Short for high-efficiency particulate air, HEPA filters can capture more particles at a quicker rate than electrostatic purifiers. However, the technology between these two types of filtration systems isn’t quite so straightforward. Both electrostatic and HEPA purifiers have a wide range of filtration methods, some of which are more effective than others.

“The precursor to HEPA filter air purifiers, electrostatics clean the air by charging airborne particles with static electricity as they enter the unit and then attracting those particles to a collector while the cleaned air continues out and back into the room,” says Vicki Liston, writer, producer and narrator of “On The Fly…DIY,” an award-winning home improvement show. “Even though HEPA filters have since entered the scene and boast a 99% removal of all air particulates larger than .03 microns, electrostatic air purifiers arguably still hold their own as an affordable alternative. They are also eco-friendly as you won’t be discarding filters to be sent off to a landfill.”

Purifiers are often seen as useful for helping those with allergies, but they actually can be useful in any indoor space. In addition to helping ensure your air is pure and breathable, they can also keep odors at a minimum, which is especially useful if you have pets or regularly cook meals. If you have an area where cigarette or cigar smoke is an issue, a purifier can help with that, as well.

One area where HEPA typically excels compared to its non-HEPA counterparts is in eliminating the smallest particles from the area. HEPA filters can usually get rid of the most microscopic filters, while other purifiers struggle. Also, look for technology that can convert ozone and smog into oxygen for even better-quality air.

The Electrostatic Air Purifier Buying Guide

  • As you’re weighing HEPA filtration against electrostatic air purification, there are benefits to electrostatic units. One of the biggest is that you don’t have to fuss with disposing of and purchasing new filters. Simply clean the filter as directed in the user manual.
  • But, as Liston explains, electrostatic air purifiers do have a downside in that some produce ozone. If you have asthma issues or sensitive lungs, you may find your issue is exacerbated by the very thing you’ve purchased to fix it.

“This ozone — also dressed up as ‘activated oxygen’ in some product descriptions — can react with chemicals commonly found in households, like cleaners, which will also cause lung irritation,” Liston says. “I don’t recommend electrostatic air purifiers at all for anyone with lung sensitivities, allergies, or asthma. Instead, opt for a HEPA air purifier if you fall into this category.”

  • Before you buy, consider where you’ll be using your purifier. Some are built to handle large spaces while others can only purify the air in smaller rooms.
  • If you’ll be sleeping or working in the room where your air purifier will be set up, make sure you choose one that operates quietly. You may, however, prefer an air purifier that emits white noise, similar to a fan.
  • Another benefit of electrostatic air purifier is energy consumption. High-powered HEPA purifiers can run up your utility bill, so if you opt for a HEPA unit, pay close attention to energy ratings.
  • Whether your purifier has a filter that needs to be changed or cleaned, an alert can come in handy. Some purifiers also provide alerts related to air quality.
  • Some air purifiers have a night light included, which can be useful if you’re keeping them in a bedroom. However, some lights can be extremely bright. A purifier with a light you can dim or turn off will keep you in control of your environment.
  • Auto-adjustment is a valuable feature in an air purifier. It ideally will be able to detect the pollutants in its surroundings and provide the level of purification necessary.
  • If you do opt for an electrostatic air purifier that emits ozone, avoid confining it to a closed-off small room.
  • To qualify as true HEPA, a filter must pass a test that demonstrates it can clean at least 99.97% of airborne particles that are as small as 0.3 microns. If you suffer from health issues, look for a system that has been certified by the Asthma and Allergy Foundation of America.
