Surround Air Purifiers Detailed Reviews Surround Air s2000 small



Model: Surround Air Purifier
Multi-Tech S2000
Last Reviewed: 02-23-2008
Rating Score: 65/100 points

Summary: Surround Air's motto is proven + affordable air purifiers. The S2000 is a basic room air purifier that works mainly on particles in the air. For basic cleaning of dust, pet dander, and pollens this model will help. The ionizer aids smaller particles in sticking to the 99% HEPA filter. Don't expect miracles at this price range, but expect a good basic cleaning. The price range is towards the low end of what I would recommend, but for the money this model does a good job.

Basic Specifications: The Multi-Tech S2000 Surround Air Purifier is designed for smaller spaces up to 300 sqft. This purifier is mainly passive with some negative ionization occurring inside and outside the purifier. The Multi-Tech S2000 uses a 3-step process. Step 1 is the pre filter capturing the largest particles. Step 2 is the 99% HEPA filter that traps particles. Step 3 is negative ionization which mainly helps the efficiency of the 99% HEPA filter. This is not a true HEPA filter, but is washable and amplified by the ionization. I am not a huge fan of negative only ionization (see ionization section), but in this case most occurs inside the unit. The only replacement part is the HEPA filter at two year recommended intervals and that could be prolonged by careful cleanings; cost = $29.99. This purifier offers a 3-year warranty. Expect some outgasing from plastic surfaces.

Rating Factors:

1) Value: 16/24 points - The MSRP is $149. The estimated square footage cleaned is 300 sqft. The Value equation is as follows: 100 * (1 - ((($149 initial + $53.80/year)/300 sqft)/4 removal points)) = 83.10. 83.10 = 16 points - Good Value.

2) What is Removed: 4/16 points - Removal of Larger Particles >0.3 microns - Good Removal, 2-points. Removal of Smaller Particles <0.3 microns - Fair Removal, 1-point. Removal of Odors and Gases - Poor Removal, 0-points, Removal of VOCs - Poor Removal, 0-points, Removal of Basic Microorganisms - Fair Removal, 1-point, Removal of Advanced Microorganisms - Poor Removal, 0-points.

3) Yearly Operating Costs: 12/15 points - The 99% HEPA filter is a washable filter; however, they do recommend replacing every two years at $29.99/2 = $14.99/year. Calculating electricity usage: 50 watts/1000 x $.0886/kwh x 24 hours/day x 365 days/year = $38.81/year. Total cost $53.80/year. Inexpensive to operate.

4) Quality: 8/12 points - Generally good use of materials; excellent website and documentation. Fit, Finish, and Workmanship - Good Quality, 3-points. Cleaning Technologies - Good Quality, 3-points. Support Material - Excellent Quality, 2-points.

5) Warranty: 6/8 points - This purifier has a 3-year warranty; replaceable parts excluded. They have a 90-day replacement period which provides a new purifier if anything goes wrong. They also offer a 30-day return period. Very Good Warranty.

6) Maintenance and Cleaning: 5/6 points - There is little maintenance other then replacing the HEPA filter when too dirty to clean. Easy Maintenance, 3-points. The HEPA filter is washable and should be cleaned as needed. Clean every 2-3 months or as needed. Wipe rest of machine and rinse pre-filter as well. Total time 15-30 minutes every 2-3 months. Average Cleaning 2-points.

7) Look and Feel: 4/6 points - One step better than a typical "box-like" purifier. Looks Good, 2-points. The controls are located near the top and the LCD panel is easy to read. Weighs 13 lbs and measures 19" X 16.5" X 10.25". Feels Good, 2-points.

8) Years in Business: 4/5 points - Surround Air Purifier is a division of Indoor Purification Systems, Inc. which has been in the air purifier business since 1998. They are located in Layton, UT.

9) Noise Level: 3/5 points - This purifier has average fan noise. Average Noise Level.

10) Set-Up: 3/3 points - Easy Set-up.

total = 65/100 points

Conclusion: A basic permanent 99% HEPA aided by ionization.

Summary: Surround Air's motto is proven + affordable air purifiers. The S3000 is a basic room air purifier that works on particles and odors/gases in the air. For basic cleaning of dust, pet dander, and pollens this model will help. The ionizer aids smaller particles in sticking to the 99% HEPA filter. In addition to what the S2000 offers, the S3000 has a carbon filter, UV lamp, and photocatalyst filter aiding in additional cleaning. Although there are several technologies at work here, don't expect miracles at this price range. Expect a good basic cleaning. The price range is towards the low end of what I would recommend, but for the money this model does a good job.

Basic Specifications: The Multi-Tech S3000 Surround Air Purifier is designed for smaller spaces up to 300 sqft. This purifier is mainly passive with some negative ionization and oxidizing agents occurring inside and outside the purifier. The Multi-Tech S3000 uses a 6-step process. Step 1 is the pre filter capturing the largest particles. Step 2 is the 99% HEPA filter that traps particles. Step 3 is a thin carbon filter. Step 4 adds a Photocatalytic Oxidation Filter aiding in odor and bacteria removal. Step 5 is a germicidal UV lamp reducing microorganisms. Step 6 is negative ionization which mainly helps the efficiency of the 99% HEPA filter. This 99% HEPA is not a true HEPA filter, but is washable and amplified by the ionization. I am not a huge fan of negative only ionization (see ionization section), but in this case most occurs inside the unit. The replacement parts include the carbon filter $9.99 X 2 = $19.98/year, the Photocatalytic Filter at 14.99/year, the UV lamp at $14.99/year, and the HEPA filter at two year recommended intervals and that could be prolonged by careful cleanings; cost = $29.99.

Model: Surround Air Purifier
Multi-Tech S4000
Last Reviewed: 02-23-2008
Rating Score: 55/100 points

Summary: The S4000 actually does a better cleaning job then the S2000 or S4000, but has a higher initial cost and much higher ongoing costs. Overall the value is a little lower because of these factors. Again, we have multiple technologies at work here, but they are all on the low-end of efficiency. This unit will clean and even do a decent job, but do not expect it to compete with some of the higher priced, quality brands. This purifier is fair for the price, but others exist that are better values.

Basic Specifications: The Multi-Tech S4000 is designed for spaces up to 400 sqft. This purifier is mainly passive with some negative ionization and oxidizing agents occurring inside and outside the purifier. The Multi-Tech S4000 uses a 6-step process. Step 1 is the pre filter capturing the largest particles. Step 2 is the true 99.97% HEPA filter that traps particles. Step 3 is a thin carbon filter. Step 4 adds a Photocatalytic Oxididation Filter aiding in odor and bacteria removal. Step 5 adds two germicidal UV lamps reducing microorganisms. Step 6 is negative ionization. I am not a huge fan of negative only ionization (see ionization section), but in this case most occurs inside the unit. The replacement parts include the pre filter at $19 X 2 = $38/year, the Photocatalytic Oxididation/Carbon filter at $39/year, the 2 UV lamps at 2 X $19.50 = $39/year, and the HEPA filter at $39 X 2 = $78/year. This purifier offers a 3-year warranty. Expect some outgasing from plastic surfaces.

Rating Factors:

1) Value: 12/24 points - The MSRP is $299. The estimated square footage cleaned is 400 sqft. The Value equation is as follows: 100 * (1 - ((($299 initial + $287.14/year)/400 sqft)/7 removal points)) = 79.07. 79.07 = 12 points - Fair Value.

2) What is Removed: 7/16 points - Removal of Larger Particles >0.3 microns - Good Removal, 2-points. Removal of Smaller Particles <0.3 microns - Good Removal, 2-points. Removal of Odors and Gases - Fair Removal, 1-point, Removal of VOCs - Poor Removal, 0-points, Removal of Basic Microorganisms - Good Removal, 2-points, Removal of Advanced Microorganisms - Poor Removal, 0-points.

3) Yearly Operating Costs: 3/15 points - 99.97% HEPA filters last 6-12 months = $39 X 2 = $78/year. TIO2/Carbon Filter lasts 12 months = $39/year. Pre-filter lasts 6-12 months = $19 x 2 = $38/year. UV lamps (takes two) last 12 months = $39/year. Calculating electricity usage: 120 watts/1000 x $.0886/kwh x 24 hours/day x 365 days/year = $93.14/year. Total cost $287.14/year. Expensive to operate.

All tasks are easy, but there are a few items to monitor here. Average Maintenance, 2-points. Cleaning is limited to wiping down and inspecting individual components for replacement. Easy Cleaning 3-points.

7) Look and Feel: 4/6 points - This unit looks more modern then the S2000 or S3000. It looks like a cross between an old radio and some kind of a mini-furnace. Looks Good, 2-points. The control display is on the front and may be more difficult to read if standing. If you are sitting, it will be easy to read/ change. Weighs 24 lbs and measures 25" X 16.5" X 9.5".

Summary: The Intelli-Pro XJ-3800 is a "futurized" looking unit designed to monitor air quality, performance, and filter life. It does incorporate multiple cleaning technologies with each one working to clean a specific set of pollutants in the air. These technologies do work, but are on the inexpensive side as the price suggests. This unit is above average and offers some value, but again do not expect it to compete with most units twice its cost. If you keep it maintained and clean it will serve you with basic overall cleaning.

Summary: The N-Lite 5000 is an attempt to put multiple technologies into a smaller purifier. They did not completely succeed at producing a super purifier; however, they did not fail either. It is a small, average purifier, providing some particle removal, some odor and gas removal, and some microorganism reduction. Being a small unit reduces the overall effectiveness and should be considered when selecting this purifier. Use for the smallest of spaces, light contamination areas, or if on a tight budget. A decent light duty model.

Basic Specifications: The N-Lite 5000 is designed for spaces up to 150 sqft. This purifier is mainly passive with some negative ionization and oxidizing agents occurring inside and outside the purifier. The N-Lite 5000 uses a 5-step process. Step 1 is a thin carbon filter.

I am not a huge fan of negative only ionization (see ionization section), but in this case most occurs inside the unit. The replacement parts include the Photocatalytic Oxididation Filter at $9.50/year, the UV lamp at $15/year, and the HEPA/Carbon filter at $36/year. This purifier offers a 3-year warranty. Expect some outgasing from plastic surfaces.

Rating Factors:

Rating Score: 63/100 points

Summary: If I compare this unit head-to-head with the N-Lite 5000, the N-Lite 5000 wins hands down. Sometimes I question why companies have so many different units or even duplicate units that seem to serve the same market segment. The XJ-2100UV does have a few distinct differences in the technology it uses, but the end results are lesser than the N-Lite 5000. If I were this company I would focus my technologies and have a strong line that represents a focus. This unit would probably get cut.

Basic Specifications: The XJ-2100UV is designed for spaces up to 150 sqft. This purifier is mainly passive with some negative ionization occurring inside and outside the purifier. The XJ-2100UV uses a 3-step process. Step 1 is a germicidal UV lamp reducing microorganisms. Step 2 adds an electrostatic precipitator with collection plates. Step 3 is negative ionization. I am not a huge fan of negative only ionization (see ionization section), but in this case most occurs inside the unit. The only replacement part is the UV lamp at $15/year. This purifier offers a 3-year warranty. Expect some outgasing from plastic surfaces.

Rating Factors:

Model: Surround Air Purifier XJ-800 for Vehicles
Last Reviewed: 02-23-2008
Rating Score: 62/100 points

Summary: This is a very inexpensive purifier that could double as a travel model. I question the durability, but the price is definitely right. If you want to gamble on longevity and want a light duty auto purifier, this one may be worth a try. There are better auto units available, but not at this price.

Basic Specifications: The XJ-800 Surround Air Purifier is designed for most small autos. It could double as a travel purfier with the extra wall adapter ($15). Don't expect complete air cleaning, but some protection is available with the ionization and ozone output. The fragrance packets are a counterproductive waste of money. I always cringe when any air purifier company offers these as it makes me wonder if they understand clean air. If you want to buy from this company, just pretend you did not hear about the fragrance packets. A 1-year warranty is standard.

Rating Factors:

1) Value: 12/24 points - The MSRP is $19.99. The wall adapter is an extra $15. The estimated square footage cleaned is 25 sqft. The Value equation is as follows: 100 * (1 - ((($19.99 initial + $2.33/year)/25 sqft)/3 removal points)) = 70.24. 70.24 = 12 points - Fair Value.

3) Yearly Operating Costs: 15/15 points - The fragrance Refill Packets are $2 each, but are not recommended. Calculating electricity usage: 3 watts/1000 x $.0886/kwh x 24 hours/day x 365 days/year = $2.33/year. Total cost $2.33/year. Very Inexpensive to operate.
