The FBI is examining the remains of the first balloon down.
The White House said there was no evidence linking the three aircraft shot down by the US military over the weekend to alleged Chinese espionage.
The objects “could be tied to commercial or research facilities and therefore harmless,” spokesman John Kirby said.
US and Canadian officials have yet to locate or recover the remains of the three downed objects.
The government in Beijing accused the United States of having done so “a trigger-happy overreaction”.
China has denied that one of its balloons, destroyed by a US fighter jet off South Carolina earlier this month, was used for espionage.
Instead, he claimed it was a weather surveillance plane that went off course.

White House spokesman John Kirby said the objects “may be associated with commercial or research facilities.”
At Tuesday’s news conference, Kirby said it was difficult to determine the purpose or provenance of the other three objects until the remains were found and analyzed.
“We have seen no evidence or anything to suggest that these three objects were part of the People’s Republic of China’s espionage program. [RPC] or engaged in outside intelligence efforts,” the White House National Security Council told reporters.
Until now, no company, organization or government has claimed the objects.

“We are doing everything we can to ensure that the airspace is clear and the background is clear up to the maximum effective range of the missile. And in that case the missiles land or the missile landed harmlessly in the waters of Lake Huron.” .
A spokesman for the Chinese Foreign Ministry, for his part, criticized the US reaction.
“Many in the US have been wondering, ‘What good can such an expensive measure do for the US and its taxpayers?Wang Wenbin explained on Tuesday.
