How much coverage do you need? Should you buy a small portable unit or a larger system? Do you need a traditional filter? What technology should you look for? How important are maintenance, noise, placement and operating costs?<\/p>\n
The right answer depends on your home, your indoor-air concerns and the area you want to treat<\/strong>.<\/p>\nAlpine Air Technologies offers a range of Living Lightning™ air purifiers designed for different applications, from the Single Room LA-500 v3.0<\/strong>, listed for 20\u2013500 square feet, to larger models such as the Fresh Air LA-3500 v2.0<\/strong>, listed for 20\u20133,500+ square feet.

Alpine itself notes that environment, airflow and pollution conditions affect the number and size of units needed.<\/p>\n
\nWhat Should You Consider When Buying an Air Purifier?<\/h1>\nBefore looking at individual models, consider these ten factors:<\/p>\n \n- Room size<\/strong><\/li>\n
- Type of pollutants<\/strong><\/li>\n
- Purification technology<\/strong><\/li>\n
- Coverage<\/strong><\/li>\n
- Maintenance<\/strong><\/li>\n
- Noise<\/strong><\/li>\n
- Placement<\/strong><\/li>\n
- Number of rooms<\/strong><\/li>\n
- Operating requirements<\/strong><\/li>\n
- Local regulations and restrictions<\/strong><\/li>\n<\/ol>\n
Let’s look at each one.<\/p>\n
\n1. Start With the Size of Your Room<\/h1>\nOne of the biggest mistakes people make when buying an air purifier is choosing a model based only on price or appearance.<\/p>\n Instead, start with square footage<\/strong>.<\/p>\nFor a rectangular room:<\/p>\n Length \u00d7 Width = Square Feet<\/strong><\/p>\nFor example:<\/p>\n 20 ft \u00d7 15 ft = 300 sq. ft.<\/strong><\/p>\nIf you’re trying to treat a 300-square-foot bedroom, you don’t necessarily need the largest purifier Alpine makes.<\/p>\n On the other hand, a small purifier designed for a single room shouldn’t automatically be expected to provide equivalent coverage throughout a large house.<\/p>\n Alpine’s catalog provides specific coverage ranges for its different models.<\/p>\n
\n2. Identify What You Want the Air Purifier to Address<\/h1>\nNot every homeowner has the same indoor-air concerns.<\/p>\n You may be shopping because of:<\/p>\n \n- Dust<\/li>\n
- Pollen<\/li>\n
- Pet dander<\/li>\n
- Smoke<\/li>\n
- Tobacco smoke<\/li>\n
- Household odors<\/li>\n
- Cooking odors<\/li>\n
- Chemical odors<\/li>\n
- Stale indoor air<\/li>\n
- Mold or mildew concerns<\/li>\n
- General indoor-air quality<\/li>\n<\/ul>\n
Alpine’s product information specifically discusses several of these pollutants and applications across its product line.<\/p>\n The important question is:<\/h3>\nWhat problem are you trying to solve?<\/strong><\/p>\nIf your primary concern is pet dander, for example, look at a purifier’s ability to address airborne particles and make sure you also vacuum and clean regularly.<\/p>\n If odors are your biggest concern, source control and appropriate ventilation should be considered alongside air purification.<\/p>\n
\n3. Understand the Difference Between Air Purification Technologies<\/h1>\nThere isn’t just one type of air purifier.<\/p>\n Common technologies include:<\/p>\n Mechanical filtration<\/h3>\nAir passes through a physical filter that captures particles.<\/p>\n HEPA filtration<\/h3>\nA high-efficiency mechanical filter designed to capture very small airborne particles.<\/p>\n Activated carbon<\/h3>\nOften used to help adsorb certain gases and odors.<\/p>\n Ionization<\/h3>\nUses electrically charged ions to interact with airborne particles.<\/p>\n UV technology<\/h3>\nUses ultraviolet light as part of an air-treatment system.<\/p>\n Oxidation\/ozone-generating technologies<\/h3>\nSome air-treatment systems intentionally generate ozone or other oxidizing agents.<\/p>\n Alpine’s Living Lightning™ products use technologies including ionization and, depending on model, activated oxygen\/ozone and UV-related technologies. The exact configuration varies by model.<\/p>\n Do not assume two products with the same advertised coverage use the same technology.<\/strong><\/p>\nAlways review the individual model specifications.<\/p>\n
\n4. Actual Alpine Product: Single Room LA-500<\/h1>\nBest Starting Point for a Small Room<\/h2>\nThe Single Room LA-500 v3.0<\/strong> is Alpine’s small-space model.<\/p>\nAlpine lists it for 20\u2013500 square feet<\/strong> and specifically discusses applications such as bedrooms, guest rooms, home offices, dorm rooms and other individual rooms.<\/p>\nConsider the LA-500 if you need an air purifier for:<\/h3>\n\n- A bedroom<\/li>\n
- Guest room<\/li>\n
- Home office<\/li>\n
- Study<\/li>\n
- Dorm room<\/li>\n
- Small individual space<\/li>\n<\/ul>\n
One important point from Alpine’s own product information is that the LA-500 is intended primarily for smaller spaces and can also complement a larger whole-home unit.<\/p>\n
\n5. Alpine Pass LA-1000<\/h1>\nA Step Up for Apartments and Condos<\/h2>\nThe Alpine Pass LA-1000 v2.0<\/strong> is listed for 20\u20131,000 square feet<\/strong>.<\/p>\nAlpine describes it as an option for smaller apartments, condos and studios up to 1,000 square feet.<\/p>\n It may be worth considering for:<\/h3>\n\n- Apartments<\/li>\n
- Condos<\/li>\n
- Studios<\/li>\n
- Medium-sized rooms<\/li>\n
- Small homes<\/li>\n
- Larger home offices<\/li>\n<\/ul>\n
The LA-1000 is also identified by Alpine as a filterless model.<\/p>\n California buyers:<\/strong> Alpine currently states that the LA-1000 does not meet California requirements and cannot be shipped to California. Check the current product page and applicable regulations before purchasing.<\/p>\n
\n6. Alpine Living LA-1500<\/h1>\nA Popular Middle-Ground Option<\/h2>\nThe Alpine Living LA-1500 v2.0<\/strong> is listed for 20\u20131,500+ square feet<\/strong> and Alpine describes it as an affordable option for smaller homes.<\/p>\nThis model may be worth investigating if you want more coverage than a small-room purifier provides.<\/p>\n Potential applications include:<\/h3>\n\n- Smaller houses<\/li>\n
- Larger apartments<\/li>\n
- Condos<\/li>\n
- Open living areas<\/li>\n
- Family rooms<\/li>\n
- Home offices<\/li>\n
- Connected living spaces<\/li>\n<\/ul>\n
Alpine’s product page identifies the LA-1500 as a filterless model and describes adjustable controls for the purification and fan functions.<\/p>\n California buyers:<\/strong> Alpine currently states that the LA-1500 does not meet California requirements and cannot be shipped to California.<\/p>\n
\n7. Choosing a Large-Capacity Alpine Air Purifier<\/h1>\nIf you have a large house or open floor plan, Alpine’s catalog offers several larger-capacity models.<\/p>\n These include:<\/p>\n \n- Professional LA-2000<\/strong><\/li>\n
- Silent Thunder LA-2400<\/strong><\/li>\n
- NA Flare LA-2700<\/strong><\/li>\n
- RainFresh Breeze LA-3000<\/strong><\/li>\n
- Fresh Air LA-3500<\/strong><\/li>\n
- Classic LA-3500<\/strong><\/li>\n<\/ul>\n
Alpine’s current catalog lists progressively larger published coverage ranges for these models.<\/p>\n
