Questions and answers

When does GermGuardian go on sale?
GermGuardian purifiers tend to drop in price around Black Friday, back-to-school season, and spring allergy season. Filter multipacks are often discounted alongside the units. Check the price history on each product page to see when a model last hit its low.
Where is GermGuardian cheapest?
Pricing varies by retailer and model, so compare the AC4825 and AC4820 across stores before buying. Warehouse clubs and large online retailers often undercut list price on the 22-inch towers. The price history chart shows which store has been lowest.
What is the difference between the AC4825 and AC4820?
Both are 22-inch HEPA PURE tower purifiers with three-stage filtration and a UV-C option. The AC4825 is the newer version and is the one most widely stocked; the AC4820 is the earlier model. Filter replacements differ between the two, so confirm the model before ordering filters.
Do GermGuardian purifiers need filter replacements?
Yes. The HEPA filter typically lasts six to eight months, and the charcoal pre-filter should be changed every three to four months. Replacement filters are model-specific, so match the filter to your unit's model number.
What is the return policy on GermGuardian purifiers?
Returns depend on the retailer you buy from, not GermGuardian directly. Most major stores accept unopened purifiers within 30 days; opened units may incur a restocking fee. Keep the packaging until you confirm the unit suits your room size.
